I have 2 routers. each router has a csu/dsu – wic t1 interface:
– Router 1 is connected to router 2 through a cross over cat5 cable using the csd/dsu interfaces
Router1 has the following config:
interface Serial0/0
bandwidth 1544
ip address 24.1.1.1 255.255.255.0
Router1 has the following config:
interface Serial0/0
bandwidth 1544
ip address 24.1.1.2 255.255.255.0
– I add clock rate 64000 to both routers.
Why can router 1 can not ping router 2?
Router#sh ip int brief
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 unassigned YES NVRAM administratively down down
Serial0/0 24.1.1.1 YES NVRAM down down
FastEthernet0/1 unassigned YES NVRAM administratively down down
Loopback0 unassigned YES unset up up
why the serial interfaces are down?
How can i fix it.
