Questions about SRE configurations

Devake666

Suppose a broadcasted IP packet reaches one of the integrated RJ-45 ports on a 2911 ISR G2, will it be possible to configure the router so that the other integrated RJ-45 ports, ESM/EHWIC modules installed on the router, as well as the MGF also recieve the packet? Technically, the router should act similar to a switch with the SRE behaving similar to a seperate machine connected via the MGF and other external machine connected to the ports of the router to recieve the broadcasted packet.

Also,  if SNMP traps were generated from the router,Will it be possible to send the traps from the router via the MGF to the SRE installed on the router?

Thanks you for the help.

Technically router isn't supposed to act as a switch. Routers are supposed to break broadcast domain else broadcast packets will keep on circulating forever. With that said, you can configure ip helper address so that a broadcast is not dropped when received by a router rather forwarded to a specific IP address by converting it to unicast. This packet can be sent to MGF. When the packet reaches MGF all systems connected would see the packet.

SNMP traps can be send to SRE via MGF.

Thanks
