Hi Marian, That config fragment is using a combination of autorp and static rp assignment. Unless there was an override keyword in the static configuration, the autorp config will take precedence in selecting the RP (and associated MA) since these are both for the same groups.
Most likely the VOD was describing static RP assignment first and didn't remove the static config without explaining why it wouldn't be a problem (dynamic configs for RP selection being favoured over static unless you're specifying override) Cheers, Adam On Sat, Feb 4, 2012 at 10:56 PM, Marian Franc <[email protected]> wrote: > Hi all, > > in the Frame Relay cloud (provider network) we want R6 (P router) become > RP for the provider multicast traffic through which we want to tunnel the > customers VPN generated multicast traffic.
