Re: C2503 Flash upgrade [7:57570]
Getting a 2500 to let you write to the Flash is always a challenge. I did a text capture the last time I did it and posted it on www.laganiere.net as part of the MPLS for 2500 procedure.

Re: ISDN PRI NailedUp [7:57555]
Hi, Starting in IOS 12.2(4)T they added a dialer persistent feature that does this (ignores the idle time basically). If you don't have that IOS or higher, you set the idle-time high and make sure theres some form of traffic that is considered interesting by the dialer-list defined so the idle time never expires. Also use the 'either' option on the dialer idle command so the idle timer gets reset for traffic in either direction.

This doesn't seem to be the case. CL: sure. routes placed into the routing table are subject to the rules of the protocol that places them there. I'm not clear on how R1 is "disappearing". I presume you are either unplugging it, or doing interface shutdowns. OSPF detects a directly connected interface shutdown almost immediately, and goes into its routine. Suppose instead you were to issue a "shutdown" on the R1 loopback. I "believe" that in this case, OSPF would go through its hold time process before reconfiguring. >Apparently, the route > table process waits for BGP to attempt to re-insert its routes > and only at that time does the route table remove the BGP routes > dependent on R1_lo0. This seems somewhat improper behavior. CL: why so? there are hold times to protect against flapping routes and short interruptions. this dates to the days when telco circuits might flake out momentarily. ( stop laughing. you all know as well as I do that telco networks are FAR more reliable today than they were 10 years ago. ) I'm not sure that instantaneous reconvergence is necessarily a Good Idea. > Note, this behavior is also verifiable using two static routes > pointing to two different next hops which are added/removed from > OSPF. > > 2) I boated around on the cisco web site and found the following > related URL (watch the wrap) > > http://www.cisco.com/en/US/tech/tk648/tk365/technologies_tech_note09186a0080 094823.shtml > > Now it mentions two ways for the routing table to be updated: > > * The routing protocol periodically attempts to re-insert it's > best routes into the routing table.

Boot proms from Cisco [7:57549]
Hi Can anyone direct me please; I have taken other's lead on this group's posts in contacting Cisco directly to obtain a boot prom (in this instance for a MC3810). So I phone Cisco and land up, as directed, by the credit card purchases department. A very friendly but puzzled person (maybe his first day) informs me that it is much quicker and expeditious to order online. Not meaning to disturb his coffee break any further and forcing him to have to strain himself to do this order I decided to follow his suggestion. The online ordering direct from Cisco requires a valid purchase order and customer number etc. Along all the links under purchasing I can find nothing to satisfy my requirement. This guy told me it takes 4 weeks delivery, this is not what I heard. Can anyone confirm the exact place to contact at Cisco?(incidently the number options at Cisco seem to have changed recently) Any help/ideas would be much appreciated.

iBGF and failures (with some new info) [7:57548]
I had posted earlier in the week regarding some questions about iBGP, the routing table, and convergence. Have some more information and some more detailed questions. In terms of the design, the network consists of many routers all running iBGP in a direct mesh or through route reflectors. OSPF runs under these routers and just carries loopbacks and p2p networks. All iBGP route next-hops are use the router's loopback. Now, consider three iBGP routers in this network: R1, R2, and E. R1 and R2 advertise the same set of networks: N1, N2 and N3 via iBGP. OSPF advertises R1 and R2's loopbacks and p2p networks. E is a router on the other side of the network from R1 and R2. In normal operating mode, one will find the following in router E's routing table: N1 -> R1_lo0 (via iBGP) N2 -> R1_lo0 (via iBGP) N3 -> R1_lo0 (via iBGP) R1_lo0 -> e0 (via OSPF) R2_lo0 -> e0 (via OSPF) This is as one would expect. Now, assume R1 goes down. OSPF quickly informs all networks that R1 has gone away, including it's loopback. Interestingly when I do a show ip route on E1, I see the following: N1 -> R1_lo0 (via BGP) N2 -> R1_lo0 (via BGP) N3 -> R1_lo0 (via BGP) R2_lo0 -> e0 (via OSPF) Notice that R1_lo0 is no longer a prefix that E knows how to get to. However, the iBGP next-hops continue to reference R1_lo0 as a next hop. These routes remain in E until BGP figures out, via BGP timers, that R1 has gone away. So, now the questions. 1) I *assumed* that the routing table process, once removing the R1_lo0 route, would have also removed any routes dependent on R1_lo0. This doesn't seem to be the case. Apparently, the route table process waits for BGP to attempt to re-insert its routes and only at that time does the route table remove the BGP routes dependent on R1_lo0. This seems somewhat improper behavior. Note, this behavior is also verifiable using two static routes pointing to two different next hops which are added/removed from OSPF. 2) I boated around on the cisco web site and found the following related URL (watch the wrap) http://www.cisco.com/en/US/tech/tk648/tk365/technologies_tech_note09186a0080094823.shtml Now it mentions two ways for the routing table to be updated: * The routing protocol periodically attempts to re-insert it's best routes into the routing table. This appears to be the behavior being observed with BGP above. * The second approach is where the routing table tracks when a routing protocol failed to get its route inserted into the table. The routing protocol is notified when the prefered path is removed from the route table and the routing protocol's path is then re-attempted to be inserted. Now, this is not exactly the configuration I have, but it's close. Instead of being a route learned by two different protocols, I've got two routes from the same protocol. I'd like the failed iBGP path to be removed, iBGP notified, and then have it re-insert the path to R2. Is there a way to cause this triggering event to the same protocol to happen? 3) From what I can tell "no sync" or "sync" in the iBGP config has no applicability here as the problem above is not related to the advertising of routes, but rather, it's around having BGP re-attempt to insert an updated best-path. Is there a way to tune the timers on how often BGP attempts to *insert* it's routes into the routing table? Thoughts? Curious if Juniper has the same issue.

Re: trunking over ethernet [7:57539]
On the 2611 platform, VLAN encapsulation is supported for Ethernet as of 12.1. Bridging on a subinterface is not supported until 12.2, however.

Cisco states that you need to have a FastEthernet (100 Mb/s) or above to support trunking. Hence, trunking on Ethernet (10 Mb/s) interface is not supported. However, if you have only e.g. 2 VLANs and wish to route traffic between them, you can use a router with 2*10 Mbps interface and it will still work. But if you have 10 VLANs then it would be better to get a router with 100 Mbps support and perform trunking with the switch.

Re: Simulator software for ATM devices. [7:57511]
11/16/2002 2:00am Saturday Without directly answering your question, we have NM 1HSSI & NM 1ATMT3 cards in production & in our lab along with the respective crossover cables. In preparing for the CCIE R/S lab I was glad we had the actual hardware BUT after I saw how easy they are to configure (really, just a different type of layer II) I was glad I did not drop any of my personal $$$ on that stuff. An ISDN sim is the only sim you need.
