Fix Recommendation

Create access-list to filter source-active multicast advertisements for any undesirable multicast groups and sources:

ip access-list extended in_MSDP_SA_filter
sequence 10 deny ip any host 224.0.1.3
sequence 20 deny ip any host 224.0.1.24
sequence 30 deny ip any host 224.0.1.22
sequence 40 deny ip any host 224.0.1.2
sequence 50 deny ip any host 224.0.1.35
sequence 60 deny ip any host 224.0.1.60
sequence 70 deny ip any host 224.0.1.39
sequence 80 deny ip any host 224.0.1.40
sequence 90 deny ip any 232.0.0.0 0.255.255.255

sequence 110 deny ip 10.0.0.0 0.255.255.255 any
sequence 120 deny ip 127.0.0.0 0.255.255.255 any

Check Contents

Check for SA filter on MSDP peer:

ICX# show msdp peer x.x.x.x | include Input

Input SA Filter:Applicable
Input (S,G) route-map:MSDP_SA_filter
Input RP route-map:None

If any configured MSDP peer is not configured to limit source-active messages using an inbound filter, this is a finding.
