![]() Next step I will try to connect a router to replace 6504 and then 3560 to check which is not working properly. I tried to check on VRRP/GLBP but 3560 doesn't know those two. The ios is loaded in native mode in RP and SP and is the latest ios. I am wondering if this is a bug or the cisco 6504 with sup 720 MSFC3/PFC3A needs a special command. I even tried today on dynamips 2x cisco 7200 and it worked flawless. I tried the same scenario many times and more complex. When I ping 224.0.0.2 on both routers they reply. The link between them doesn't go thru a switch. I tried access interface, routed interface, trunk interface, access port channel, trunk port channel, routed port channel, no firewall on the line, there are no access-lists, no special configurations because the configuration was erased before. It doesn't see incoming multicast HSRP hellos, but EIGP adj is up and no issues. and sh standby brief:Īlso 6504 displays debug messages that he receives multicast from 3560 and sends multicast to 3560.īut 3560 sees only outgoing multicast to 6504. I can see packets inbound and outbound vlan 100 for 224.0.0. When prio = 100 on both routers, 3560 is favored to be active router because of higher ip address. When issuing sh ip int vlan 100 on both, I can see the same configuration (including 224.0.0.2 for HSRP and 224.0.0.10 for EIGRP) I have configured HSRP between G3/ - > G0/: The scenario is like this: cat 6504 with 2xsup720 redundant connected to 3560. I am not a beginner on cisco networking, but today I had an issue with HSRP. ![]()
