Got a 3750 with a bunch of multicast sources on it coming from Vlan101 and Vlan99:
int vlan99 ip address 10.16.99.1 255.255.255.0 no ip redirects no ip proxy-arp ip pim sparse-dense-mode load-interval 30 ! int vlan101 ip address 10.0.0.202 255.255.255.0 no ip redirects no ip proxy-arp ip pim sparse-dense-mode load-interval 30 ! My destinations for this are some routed interfaces on the 3750: interface GigabitEthernet2/0/2 no switchport ip address 10.255.255.1 255.255.255.0 ip access-group customer-in in ip access-group bl-out out ip pim sparse-dense-mode ip igmp static-group 225.101.4.2 ip igmp static-group 225.101.4.4 ip igmp static-group 225.101.4.5 ip igmp static-group 225.101.4.17 ip igmp static-group 225.101.4.30 ip igmp static-group 225.101.4.58 ip igmp static-group 225.101.4.8 ip igmp static-group 225.101.4.104 ip igmp static-group 225.100.4.2 ip igmp static-group 225.100.4.4 ip igmp static-group 225.100.4.5 ip igmp static-group 225.100.4.17 load-interval 30 speed nonegotiate ! ip access-list extended bl-out deny igmp any any deny pim any any permit ip any 225.100.4.0 0.0.0.255 permit ip any 225.101.4.0 0.0.0.255 ip access-list extended customer-in deny ip any any ! My problem here is when we turn this up, no matter what is setup on the interface (even pim neighbor filters, the acl, etc) the far-end sees a PIM neighbor form and the 3750 becomes the DR which effectively breaks the rest of their multicast: Jan 9 01:18:28.037 CST: %PIM-5-NBRCHG: neighbor 10.255.255.1 UP on interface Vlan100 (vrf default) Jan 9 01:18:28.041 CST: %PIM-5-DRCHG: DR change from neighbor 10.0.0.1 to 10.255.255.1 on interface Vlan100 (vrf default) The 3750 never sees a neighbor come up, but that log is from their 7600, after they see this, everything breaks... Any clue? _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
