HSRP a travÃ131;©s de un backbone 3COM 4226

Hola a todos,
soy nuevo aquí y quería ver si alguien tiene alguna opinión sobre esto. Algún caso de éxito trabajando con HSRP en routers Cisco a través de un backbone 3Com 4226? Este 3Com por defecto viene con el IGMP habilitado, lo que ocasiona problemas al HSRP en vez de eficiencia, los hello packets son filtrados por el 3Com. Deshabilitando el IGMP el HSRP funciona correctamente, al menos aparentemente. Luego de unas horas ocurre un bloqueo de las puertas del 3Com donde están conectados los routers Cisco, es decir, dejan de forwardear paquetes. Reseteando el 3Com se restablece la comunicación.

Alguna idea de lo que ocurre o sencillamente no se puede trabajar con 3Com como backbone para solución de alta disponibilidad de Cisco con HSRP?

gracias de ante mano y espero no haberlos aburrido.

Re: HSRP throught backbone 3COM 4226

Sorry, I was wrong language.

I'm new here. I want to know if you have opinions about to use a backbone 3COM switch 4226 to Cisco solution high Availability HSRP. I have difficulties for work in this case.
In default parameters on switch 3Com 4226 is enable IGMP protocol, however, not work with the multicast packets HSRP because filtering this packets.
Partial solution is disable IGMP, then multicast packets are forwarded and the HSRP protocol between both routers Cisco operate ok, but in few hours, this ports in switch 3COM are blocked to forward any packets. I should reset the 3Com switch

Do you have any idea of the origin of the problem?

thank you very much for your help !!!
