HI All,
Has anyone seen this before?
I have R2 and R6 connected with each other via a 3550.
Rack1R2 -----3550------------------Rack1R6(fa3/1/0.26)
|
ISL trunk
If I enable HSRP on R2 and R6 all connection is lost between them.
If I then change the trunk encap to dot1q on R6 and the 3550, all works
fine.
Does anybody know why this is??
Rack1R6#
interface FastEthernet3/1/0.6
encapsulation isl 6
ip address 130.1.26.6 255.255.255.0
no ip redirects
End
Rack1R6(config)#int fastEthernet 3/1/0.26
Rack1R6(config-subif)# standby ip 130.1.26.254
