can 2 subinterfaces point to the same ip unnumbered fastethernet0/0 port on a router. Will this cause any issues? I need to do this while we change over to a new DS3 and keep our current DS3 up and running temporarily. As soon as I switch over to the new dlci, I will put the old dlci in shut on our core router.
Example:
interface Serial0/1/0.1 point-to-point
description connected to test
ip unnumbered FastEthernet0/0
no ip mroute-cache
frame-relay interface-dlci 100
!
interface Serial0/1/0.300 point-to-point
description connected to test
ip unnumbered FastEthernet0/0
no ip mroute-cache
frame-relay interface-dlci 300
