Re: max number of Sub interfaces [7:45288]
Steven, I supposed it would really depend what else you're doing on the device. I've worked with a pair of 3640s that each had 300 or so sub-interfaces on them, running just EIGRP on the routers and they didn't miss a beat. If each of those sub-interfaces also had crypto running on them, I'm sure that would be another story!!! :) thanks, -Brad Ellis CCIE#5796 (R&S / Security) Network Learning Inc [EMAIL PROTECTED] www.optsys.net (Cisco hardware) ""Steven A.

Steven, Every interfaces includes subinterface(sw), physical interface(hw), virtual/logical interface(sw) is divided into s/w & h/w category. Each Software IDBs takes ~2600bytes v/s Hardware IDBs takes ~4700bytes. No.of IDBs you want to use it depends upon your system resources have it currently, going with higher number of subinterfaces may slow down boot process since it has to nvgen configuration, slow-down other processes like "sh run" & saving configuration to nvram may not fit with or without compression, etc... thanks, rahul.

Re: ospf and sub-interfaces [7:38788]
Hi, This shouldn't be a problem. I've done it before. Just make sure the native VLAN is the same on each 802.1q connection (ie: switch port and router port connecting to each other are in same native VLAN). If you have a newer router IOS you can do a 'encaps dot1q # native' command. Older IOS's didn't have the native keyword. If you don't have the IOS with the native keyword you can put the native VLAN IP on the main interface which will be native VLAN. You might also want to hard-code the trunk to on instead of auto/desirable and turn channeling off and hardcode the speed/duplex.

I'm looking at an design where there's a hub-spoke network based on 802.1q. Specifically, there will be a number of routers connect back via FE/GE into a central router through an 802.1q trunked interface. Each remote router will run OSPF and thus should form an OSPF adjancency with the central router over its respective sub-interface. Any issues or gotchas with this?

RE: Can frame-relay multipoint sub-interfaces support inverse [7:28373]
there are some points in Caslow that are not applicable to IOS 12.x and higher. this is one of them. everyone should be aware that Cisco has changed a number of things beginning with 12.x, some for the good, like this particular issue, and some not for the good, like the requirement that wildcard masks be contiguous. So - for IOS 12.x, you can have both frame maps and inverse arp operating simultaneously. unless of course you invoke the no frame inverse-arp command on the interface. Which you may want to do. sometimes there is a phantom mapping of 0.0.0.0 to a dlci or two should have seen Val's face the first time he saw this in ECP1 class ;-> I seem to recall running into this issue recently.

A router has never been able to detect duplicate IP addresses. It's not its job. When the first packet comes in to the router from one of the devices assigned to 10.10.1.5, the router would add the source addresses to its ARP cache (assuming it's doing ARP gleaning) or the first time it sent to the IP address it would ARP and get the MAC address from the first response. If you use DHCP you shouldn't get duplicates anyway. DHCP checks for duplicates.

Keep in mind that one routes between IP subnets, not VLANs. VLANs are a layer two concept. From there you should be able to answer you own first question. In the second case, given IP subnets have unique ranges, only on PC will be on the valid subnet and hence be able to communicate to the rest of the network.

How does the external Router decide how to route the packets between the > VLANs, is the INTERVLAN routing based on the IP address assigned to > sub-inteface? Yes, The router will make a decision on which interface to use based on the destination IP address of the Packet it is routing. Either by a connected network or the next hop according to the routing table. If it's a trunk interface with subinterfaces, same thing applies except the router will encapulate the packet in the proper frame (ISL or Dot1Q) > 2.

The router doesn't disable hosts. If you assign a ip address to an interface on a router and a host already has it, the router will tell you with a consol message. It will ARP for the address it you assigned it to see if there is a duplicate. Same thing with hosts. Depending on the OS, If you assign an address that is already in use on the network, you will get an error message like a " pop up" in winblows. Host ususal do an ARP for it's address just like a router. Appletalk works in the same way, sort of. It actual can randomly pick it's own host address in the cable range and checks to see if its in use, If it is, it try's another one. Hope this helps.

InterVLAN routing & VLAN Sub-Interfaces [7:16445]
Hi I was studying the InterVlan routing documents and I got to some questions. In a scenario like the attached file: 1. How does the external Router decide how to route the packets between the VLANs, is the INTERVLAN routing based on the IP address assigned to sub-inteface? 2. In these scenarios, how does the router detect a conflicting IP address? For example, if each IP subnet is assigned to a VLAN( 10.10.1.0 to VLAN 1 and 10.10.2.0 to VLAN 2), if two computers on both VLANs are assigned the same IP address (for example 10.10.1.5), how is the confilit detected and which computer is disabled?

Re: Setting up Sub-interfaces on serial interface for Frame [7:9713]
I saw this a year or so ago when cleaning up some older IOS version routers, when working some T-1 disconnects. I could not explain it, except that it was some sort of IOS hold on the config. I think a reload was the solution. One router needed a write erase to wipe the config. What IOS are we dealing with ??? I think mine were all 11.2 something...

RE: Setting up Sub-interfaces on serial interface for Frame [7:9704]
Well, since you say you have everything else accounted for, have you tried rebooting the router? Subinterfaces and loopbacks tend to be rather troublesome once setup. Deleting and changing these virtual interfaces typically requires a reboot for the changes to take effect completely. You might also check that "ip subnet-zero" is turned on. If not, you will get that very message if you try to use the zero subnet.

Re: Sub-interfaces and Secondary interfaces
I have a tidbit to add. Multicast is not supported on secondary networks. So you can't support protocols that use multicast on the secondary network such as WCCP or H323. Or at least you'll have to configure unicast connectivity for things like OSPF or EIGRP.

Re: Sub-interfaces and Secondary interfaces
You really do not have a lot of choice in the matter. The subinterface configuration can not be use unless you are running ISL encapsulation (vlans) or a point-multipoint type network on the interface. If you try to use the sub-interface setup without these the router will give you an error. Makes your decision easy.

Re: Secondary vrs sub interfaces
I think you may be referring to secondary networks for an Interface
and then Sub-interfaces.
Secondary refers to secondary network or IP for an interface. Say you
want to assign more than (1) IP or block of IP's to an interface what
already has an IP address/block assigned.. say.:
interface Ethernet 0
ip address 10.0.0.1 255.255.255.0
To add another IP or block to the interface you would do the
following:
ip adress {network} {netmask} secondary
making..
interface Ethernet 0
ip address 10.0.0.1 255.255.255.0
ip address 192.168.0.1 255.255.255.0 secondary
Now you'll have 2 networks directly connected to Ethernet0 in your
route table.
Sub-Interfaces -
I've only used sub-interfaces in a frame-relay scenario. Say you
have multiple branch offices which are all connected via Frame Relay.
In order to communicate with them you need FR PVC's mapped to all of
them throughout the frame cloud, not necessarily full mesh.. :). Each
PVC will have a separate DLCI pair describing essentially
entrance/exit points in the network. You will need to build
frame-relay subinterfaces with a dlci to distinquish each branch
office connection for the other.
Say.
interface Serial0.1 is used to connect to BranchA
interface Serial0.2 is used to connect to BranchB
interface Serial0.3 is used to connect to BranchC
In turn.. BranchA will need an sub interface with DLCI configured to
speak with Branch B and so on..
Hope that make sense.. If not I'm sure someone on here can straighten
me and you out..
Cheers.

Re: Sub Interfaces
hi Brian. I have a quick question from what you mentioned regarding multipoint subinterface that I have always been wondering about. You mentioned, "Point to multipoint" and it can communicate with many routers within that same subnet." Let's say there is a router in a headquarter, and 2 routers in a branch office, so let's say there are three interfaces are participating in Frame-Relay. My quick question is; Are you saying that these three participating interfaces should be in the same subnet in order to communicate? What if they are not in the same subnet? Could you make it clear for me? Thanks jeongwoo --- Brian <[EMAIL PROTECTED]> wrote: > On Sat, 28 Oct 2000, Austin wrote: > > > Hi Group (Brian, Tim Brad, et al.) > > > > Thank you all for your help.

Re: Sub Interfaces
you can define a subinterface to be "multipoint" instead of " point-to-point". then instead of using "frame-relay interface-dlci x" use multiple "frame-relay map" commands under that subinterface definition. apply an IP address to the subinterface, and the IP addresses on the other side of the PVCs must all be in the same subnet.

Re: Sub Interfaces
Austin, This response is in a bit more detail than the others but I think it's worth it. As another option you can also specify multiple dlci's and still use the "frame-relay interface-dlci xxx" -- once for each dlci. This will allow you to continue to use dynamic mapping vice static map statements. The "hub router's" subinterface which communicates with the others would be multipoint and the "spoke" subinterfaces would be point-to-point. To try this example, you can use a router to act as a frame relay switch with 3 other routers hanging off--the "frame-relay route" commands on the frame-switch (a 4500 in this case) would look like this: hostname FrameSwitch ! int s0 ! Spoke A hangs off here frame-relay route 100 interface s2 200 ! int s1 ! Spoke B hangs off here frame-relay route 300 interface s2 400 ! int s2 ! "Hub router C" with point-to-miltipoint sub-int ! frame-relay route 200 interface s0 100 frame-relay route 400 interface s1 300 ! Note there's a frame route to AND from each dlci--also keep in mind using a router as a frame relay switch is a practice for a lab enviornment. ! ! interface commands and the result of a sh frame-relay map on the hub router: ! interface Serial0.3 multipoint ip address 172.0.5.1 255.255.255.0 frame-relay interface-dlci 200 frame-relay interface-dlci 400 ! Serial0.3 (up): ip 172.0.5.2 dlci 200(0x1F7,0x7C70), dynamic, broadcast,, status defined, active Serial0.3 (up): ip 172.0.5.3 dlci 400(0x1F6,0x7C60), dynamic, broadcast,, status defined, active ! !interface commands and sh frame-relay map on the Spoke A ! interface Serial1.3 point-to-point ip address 172.0.5.2 255.255.255.0 frame-relay interface-dlci 100 ! sh fr map Serial1.3 (up): point-to-point dlci, dlci 100(0x1F5,0x7C50), broadcast status defined, active ! !interface commands and sh frame-relay map on Spoke B ! interface Serial0.3 point-to-point ip address 172.0.5.3 255.255.255.0 frame-relay interface-dlci 300 ! sh fr map Serial0.3 (up): point-to-point dlci, dlci 300(0x1F4,0x7C40), broadcast status defined, active I hand jammed some of these commands but I have working lab configs if you're sincerely interested. The best description of just about all frame-relay options known to man is in Caslow's book "Cisco Certification: Bridges, Routers and Switches for CCIEs. If you're working with frame I hihgly recommend reading this book whether or not being a CCIE is on your list of "things-to-do" or not. Also the Cisco docs have some great examples you can work after reading the clear explanations by Caslow.

RE: Sub Interfaces (hmmm?)
Be sure to turn off ip split horizon (or apple, or ipx eigrp) on the multipoint interface. Also remember, over frame, if you are no using a sub interface on a physical interface, split horizon is off by default, always enable it on any "spoke" routers. Additionally be aware of the issues that each routing protocol has with a multipoint interface (i.e. - setting the ospf network type on the spokes and hub).

The best way to answer these questions is to just try ityou usually learn alot doing it. It is perfectly fine to use a subinterface on router 1 (in point to multipoint) to talk to an interface on routers 2 and 3 (not subinterface). The fact you are using subinterfaces or not using sub interfaces is trasparent to the distant end.

Re: Sub Interfaces (hmmm?)
I am configuring 2 sub-interfaces on the router. One subinterface for the connection to router1 and 1 subinterface for the connection to router2 and router3. I will not be configuring subinterfaces on router1, router2 and router3. Hope this gives you some more information and it is a Frame Relay environment yes.

If you run point to multipoint on a subinterface, you can map more than one dlci/destination pair. If you had 5 remotes and 5 interfaces, then you would no doubt have 5 networks, and would probably want to run point-to-point. Unless you had more than one remote on a network, then you would run point-to-multipointall I am saying is the only reason you would run point to multipoint in the first place is if you had more than one destination off a subinterface.

sure. You can do it for ethernet interface or serial interfaces. You can configure the secondary ip address on that interface.

Re: Deleting Sub interfaces
My favorite would be to make a clean config on your tftp server and then issue WRITE ERASE followd by COPY TFTP START and reload the router. That's if you can afford a reload on a production box.

Deleting Sub interfaces
If it's anything like sub-interfaces on a serial interface - no, you have to reboot the router to get rid of it completely. At least I haven't found any other way of doing it - I'd like to know if you find one though.
