Hi all.
i have a basic topology ... R3------R1
R3 is advertising himself as rp for complete block ...
ip pim send-rp-announce lo 0 scope 10 interval 5
R1 the mapping agent ..wants to filter groups from R3 ...ie R3 sould
only service 232.0.0.0 7.255.255.255
so here what i did on R1 the MA
R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#access-list 2 deny 224.0.0.0 7.255.255.255
R1(config)#access-list 2 permit 232.0.0.0 7.255.255.255
R1(config)#exit
ip pim autorp listener
ip pim send-rp-discovery FastEthernet0/0 scope 10
ip pim rp-announce-filter rp-list 1 group-list 2
R1#show ip pim rp map
PIM Group-to-RP Mappings
This system is an RP-mapping agent (FastEthernet0/0)
R1#show ip pim rp map
PIM Group-to-RP Mappings
This system is an RP-mapping agent (FastEthernet0/0)
R1#show access-lists
Standard IP access list 1
10 permit 13.0.0.3 (140 matches)
Standard IP access list 2
10 deny 224.0.0.0, wildcard bits 7.255.255.255 (20 matches)
20 permit 232.0.0.0, wildcard bits 7.255.255.255
As you can see denying only a subset of 224.0.0.0 is making it
deny complete block ...
is this normal behavior ??
Can any one try the same requirmnet and see if it works
