Re: FW: can't ping or reach serial port
I believe when you PING your own interface on a frame-relay interface, the ICMP packets are not responded to internally by the router just because you are PINGing the router's own interface. The packets are actually transported through the frame cloud to the other side and back. Therefore, I think it might be a good idea to check the access-lists on the other side of the PVC (if any access-lists exist) just to make sure.

Re: Bridging Problem using OSPF/EIGRP
OSPF and EIGRP are routing protocols (layer 3) and don't have anything to do with bridging (layer 2). You can either route or bridge a specific protocol on the same interface. If for instance you want to bridge IPX on a particular interface, then you would not assign that interface an IPX address. Hence, no routing protocols would be enabled on that particular interface. Bridging in essence is like extending your LAN so you don't need routing to get from one side of the bridge to another. You can, however, bridge a protocol on one interface and route it out another interface by confgiguring IRB (Intergrated Rotuing Bridging). This subject is a little confusing and requires some reading. There is a good chapter on it in Caslow's BRS book.

IPX-NLSP question
I'm studying for the CCIE Lab and got stuck scratching my head doing an IPX-NLSP scenario. Does anyone know how to filter sap advertisements from one NLSP area to another? I know that you cannot filter sap updates within the same NLSP area, however, according to the manual you are supposed to be able to filter sap updates at the area boundries with the distribute-sap-list [in, out] command. Has anyone done this before?? If so, I would appreciate some advise. My scenario is simply done with 3 routers r1,r2, and r3. r1 belongs to "area1" r2 belongs to "area2" and r3 is the go between (has an interface in both areas). I'm using static saps in r1 but cannot selectivley filter them on r3 so that all are not advertised to r2. r3 is basically the host router with one pvc to each of the other routers using frame-relay subinterfaces. thanks in advance, Arya Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: Please help with the routing problem
Is the IP network between routerA and routerB being routed in the Internet? Remember, when you PING, the ICMP packets use the outgoing inerface as the source IP address. Therefore when you PING from routerA your ISP would need to have a route to that IP network for the packets to find their way back.

Here is the network setup: --E0-RouterA-S0--S0-RouterB-E0--Firewall--E0-RouterC-S0---Internet The problem is that RouterA cannot access Internet. RouterB is configured with default route pointing to the firewall's LAN interface, and it can get to the Internet just fine. RouterA has default route pointing to S0 on RouterB. RouterA can ping hosts on RouterB's Ethernet subnet, but cannot ping Internet hosts. When I try to trace Internet host from it, the trace stops at the S0 interface on RouterB. The routing between A and B is EIGRP, and it is working, because routers can reach each other's Ethernet subnets. Firewall has all the ports open. It seems to me that when packets addressed to Internet from RouterA reach RouterB, RouterB does not know what to do with them. How can I fix this? Thank you. __ Do You Yahoo!? Yahoo!

Re: 2505 Router/Hub
You should think of the Ethernet0 interface as a virtual inerface. since the hub is built in, then you don't need a physical Ethernet interface. You can verfiy by doing a "no shut" on the Ethernet0 interface and watch it come up.

Re: Why the route in BGP table doesn't appear in IP table.
As far as I know 2 things could cause this. 1: You don't have a route to the next-hop address in the BGP table. 2: Has to do with the "Synchronization" rule which states that any route received from IBGP speakers would have to also been learned through an IGP. To get around this rule you could turn off synchronization under the router bgp process.

My guess would be that you have some VLANs being trunked which have not been configured on the router with the encapsulation isl command.

Re: Vlan Capable Router
In a nutshell, a VLAN capabale router is one with a FastEthernet port that can be configured for ISL or 802.q encapsulation which would connect to the trunk port of a switch. It would then be able to receive packets from the switch and be able to tell to which VLAN each packet belongs to eventhough all packets are being received through the same physical interface. It would also be needed to route between VLANs on the same switch.
