use the .255 address?

router A-------router B------router C

I try to use a 10.1.1.255/32 as a router C's loopback .

the interface between B C is 10.1.3.0/30. the interface

between A B is 10.1.1.0/30.

on router A B C use "ip classless"and " ip subnet zero"

but I find on router B ping 10.1.1.255, it always reply from

router A's interface as a broadcast address ,

"Reply to request 0 from 10.1.1.2,1 ms"

what's wrong with it? can't I use the .255 address ?

Re: use the .255 address?

Have you put static routes on B, telling it how to reach 10.1.1.255/32 or atleast a routing protocol running between routers A, B, and C. You can definitely use 10.1.1.255/32 as loopbacks ip address. Looks to me like a routing issue.

yes I put a static route on B,and the router B can see the route of 10.1.1.255 comes from C.But I only can ping the interface address of C, ping the 10.1.1.255 ,it reply from A!!!

Re: use the .255 address?

Please paste your configs, as well as snapshots of ip routes on each router A, B, C.
