Hi, I am searching for this over the internet but couldn't find a good answer: When does route-map implicit deny apply? I knew for BGP route advertisement, a no-match route is discarded with implicit deny at the end of route-map, whereas PBR skips t...

Hi guys, I having a backbone area with 2 ABRs (R4 & R1) summarizing 155.1.146.0/23 and 155.1.146.0/24 respectively. /24 is a subnet is in another area while /23 is created with "area range" command. When R5 received the LSAs it shows link ID as 155....

Hi everyone.Need you opinions for the following question. 1. When we replace a RP with another RP, is there any down time for the multicast applications. (I guess no because RP is only needed for initializing connection between source and clients, bu...

Thanks Richard, If route maps are applied in a policy-routing environment, packets that do not meet the match criteria are then forwarded according to the route table. So I guess policy-routing is the only special case or we can say "denied by PBR ...

Thanks Peter & Joseph,"This depends primarily on whether your network is configured to perform a switchover to the shortest path tree (SPT switchover), or whether it remains using the shared tree rooted at the RP"How to know whether my network has th...

Sorry if I wasted your time guysI just found out those which are listing the 2 groups as Sparse Mode were configured with the static RP 10.0.0.6And Auto RP's behavior is to ignore the 2 groups 224.0.1.40 and 224.0.1.39 then it wins over static RP for...

It's NULL because route through RP was pruned due to SPT switchover from shared stree. That happens after first few packets then source starts sending packets to receivers via their own SPT, that makes the SPT via RP unnecessary then it is pruned (ma...
