I have migrated the configuration from a 1600 to 1800 Cisco Router.

In a 1600, RIP is sending v2 update correctly. But with the same
configuration, 1800 is not sending a update.

In a debug IP RIP:

00:47:21: RIP: sending v2 update to via FastEthernet0 (
00:47:21: RIP: build update entries - suppressing null update

I have this configuration in a router 1801:

interface FastEthernet0
 ip address secondary
 ip address secondary
 ip address secondary
 ip address
 no ip redirects
 ip nat inside
 ip rip advertise 5
 ip virtual-reassembly
 ip policy route-map InterLAN
 speed 100
 no cdp enable

router rip
 version 2
 timers basic 5 15 30 60
 redistribute connected
 redistribute static
no ip classless
ip route
ip route
ip route
ip route

I recevied correctly update route from a neighbor (,
but this router is not advertised nothing!

IOS version: 12.4(2)XA ... Also update IOS router with lastest version (
12.4.4T1), but it did not work.

Somebody can help me?

Thanks in advance!
