I am connecting our campus core switch 4707r to a router through a layer 3 interface and using eigrp. I could not bring up the interfaces between the router and switch. Is there something I missed? i am using a crossover cable to connect them. any help will be appreciated. i saw the link is green on the router end.
Here is the router config:
interface GigabitEthernet0/1
description to WACAT4K-A
ip address 10.12.11.1 255.255.255.252
duplex full
speed 100
!
!
router eigrp 2
network 10.0.0.0
passive-interface default
no passive-interface GigabitEthernet0/1
here is the 4507r:
interface GigabitEthernet1/2
description WA3500-A1
no switchport
ip address 10.12.11.2 255.255.255.252
qos trust dscp
router eigrp 2
no auto-summary
network 10.0.0.0
Can I use any switch port as a layer 3 interface and connect it to a router?
thanks,
Alison
