IRDP

Here is a configuration of IRDP that I had done yesterday. It's not often that you will use this let alone remember how to do it when the time comes so I figured I would just post a working configuration.

interface FastEthernet0/0.50
 encapsulation dot1Q 50
 ip address 172.16.30.3 255.255.255.128
 ip irdp
 ip irdp multicast
 ip irdp maxadvertinterval 20
 ip irdp minadvertinterval 20
 ip irdp holdtime 60
 ip irdp preference 100

interface Vlan50
 ip address 172.16.30.10 255.255.255.128
 ip irdp
!
ip classless
ip http server
ip http secure-server
ip gdp irdp multicast
ip gdp irdp
!
sw3(config)#do sh ip route

  1. Hey! How are you?
    You sure that by enabling both "ip gdp" commands you're not only getting IRDP information via ICMP and not multicast?
    My lab worked with the exact same configuration you have. However, when I enabled debugs, I could see ICMP but not multicast packets.

    Cheers!

    P.S.: I know you posted this a looong time ago!

  2. lol...just forget it...I was debugging only SW3...R3 ICMP debug showed me it was sending multicast advertisements.

    Take care!
