Hi,
Forgot to add that using a direct crossed over connextion I get the
following arp tables:
On router A
RouterA#sh ip arp vrf VF | inc 172.21.150
Internet 172.21.150.2 0 0090.6ff6.e060 ARPA Port-channel3.1
Internet 172.21.150.1 - 0050.3e23.8860 ARPA Port-channel3.1
On router B
RouterB#sh ip arp vrf VF | inc 172.21.150
Internet 172.21.150.2 - 0090.6ff6.e060 ARPA Port-channel3.1
Internet 172.21.150.1 0 Incomplete ARPA
Any ideas ?

Funnily enough it does not work! Not even when I connect both fast Ethernets
with cross-over cables does it work.
Either I am doing something extremely stupid or else there is a hardware
failure somewhere.
Any hints please !?
Thanks in advance
