I know this was asked recently - it is NOT possible to define it using just
a priority-list with a port number, as shown in the following debug ip
packet detail (with PIM sparse-dense, Auto-RP, Mapping Agent)...
10:15:19: IP: s=10.1.5.4 (Ethernet0), d=224.0.1.39, len 28, rcvd 0, proto=2
10:15:19: IP: s=10.1.5.4 (Ethernet0), d=224.0.1.40, len 28, rcvd 0, proto=2
Protocol type 2 checks out at Internet Group Management/IGMP, TCP is type 6,
UDP is type 17, ICMP is type 1, OSPF is type 89. PIM v2 has its on protocol
type 103.
The only way to do this via a priority queue would be via an extended
access-list...
access-list 101 permit igmp any 224.0.0.0 15.255.255.255
access-list 101 permit 103 any 224.0.0.0 15.255.255.255
Then,
priority-list 1 protocol ip high list 101
Of course you can get more specific with the extended access-lists to
include only PIM specific multicast addresses.
Regards,
Adrian
