Hello, I understand how this can be confusing. From what I understand the break down occurs here.. In this scenario, reaching the vpc-peers through keepalives are achieved through keepalive links while the primary and secondary role election is established through the vpc-peer link. You must establish the first keepalive for the role election to occur in the case when a switch comes up and the vPC-peer link is up. In the sentences above they are stating what must occur for vPC peer election to happen. It reads like this to me: Keepalive messages are exchanged through keepalive links while the primary and secondary role election is established through the vpc-peer link. R ole election can only occur across the vPC-peer link when keepalive messages are exchanged across the keepalive link. When keepalives fail to reach the peer switches because the keepalive link is down, role election does not proceed and the primary or secondary role is not established on either vPC peer switch and all vPC interfaces are kept down on both switches.

spanning-tree portfast default spanning-tree portfast bpdufilter default These commands have an interesting effect. BPDUs are not sent (note a few are sent when the port is first brought online) but if a BPDU is received the port loses portfast state and begins to forward BPDUs. Much different behavior from configuration applied to interface. Regards, Ryan

Hello Andre, No, you don't need an RP but why operate in sparse-dense without an RP? All groups without an RP defined will operate in dense mode. Which is okay but dense is not suitable for large network. Where does f0/1 connect to? It looks like you are getting several group reports from 139.0.0.1 leading to the *,G. Is f0/1 where the receivers are? Ryan

If the goal is to mark cos 5 to dscp 46 and you have configured mls qos trust cos on the Nortel phone ports then the 2801 will not change the marking unless configured to do so. Is there anything else you are trying to do besides marking cos 5 to dscp 46?

Hello Jeff, MLS QoS stands for multilayer swicthing QoS. 2801 is strictly MQC. Nortel phones connect to 3750 right? Why not configure this on the 3750? Regards, Ryan

To answer your first question: To add networks to your local BGP table you can use the network command or redistribute from another protocol. This cannot be accomplished with a route-map on a neighbor statement. The route-map applies policy control mechanism to the routes leaving or entering the BGP table. Second Question: There are BGP neighbor forwarding rules which dictate what routes are shared with who but that is a little off topic. In your example your neighbor is an eBGP neighbor. The router will attempt to share the best route in the BGP table for each prefix with neighbor zzz. After this list is compiled the router will exclude the prefixes that have been denied by route-map and permit prefixes that have been permitted by route-map. In your example the route-map will prevent any routes learned from another BGP neighbor from being advertised or routes added to BGP via redistribution or network command from being advertised.

Only refrain if you don't intend to add all connected networks to OSPF. Personally I prefer statements which match each interface (e.g. 172.20.225.64 0.0.0.0 area x). It gives more control over what networks are advertised and what interfaces will form adjacencies. So earlier I said change the prefix-list from le 28 to ge or le 32. The previous output from R2 showed /32 masks for 172.20.255.x. Now I realize those are loopback interfaces without point-to-point ospf network type applied. Are you studying for a test? Ryan

Is the output above from R1 or R2. According to the attachment I was lead to believe the output was from R2. It looks like the 0.0.0.0 network statement is causing R1 to advertise those networks to R2. Correct that and I also suggest modifying the prefix-list singo. The networks are all /32 so it should be ge 32 or le 32 would also work. R, Ryan

Mohamed, I believe it has something to do with the following statement. network 0.0.0.0 255.255.255.255 area 0 This command matches all connected interfaces. R, Ryan
