[AG-TECH] Multicast

[David Sliman]

 I always try to keep to the bare minimum and I don't know if it really matters, but we have only enabled multicast on the
interfaces we are using.  It looks like all the interfaces have "ip pim sparse-dense-mode".  We have "ip pim sparse-mode"
enabled only on those interfaces that need it.

I don't see your rendezvous point and msdp statements.  Here are ours:

ip pim rp-address 131.95.1.25
ip msdp peer 131.95.1.26
ip msdp sa-filter out 131.95.1.26 list 111
ip msdp cache-sa-state
!
!
access-list 111 deny   ip any host 224.0.2.2
access-list 111 deny   ip any host 224.0.1.3
access-list 111 deny   ip any host 224.0.1.24
access-list 111 deny   ip any host 224.0.1.22
access-list 111 deny   ip any host 224.0.1.2
access-list 111 deny   ip any host 224.0.1.35
access-list 111 deny   ip any host 224.0.1.60
access-list 111 deny   ip any host 224.0.1.39
access-list 111 deny   ip any host 224.0.1.40
access-list 111 deny   ip any 239.0.0.0 0.255.255.255
access-list 111 deny   ip 10.0.0.0 0.255.255.255 any
access-list 111 deny   ip 127.0.0.0 0.255.255.255 any
access-list 111 deny   ip 172.16.0.0 0.15.255.255 any
access-list 111 deny   ip 192.168.0.0 0.0.255.255 any
access-list 111 permit ip any any
