In my router there are many multilink interfaces used to connect remote offices.

I configure each multilink interface with 30-bit subnet mask.When using the command "show ip route", there are not only

C x.x.x.0/30 is directly connected, MultilinkXX

but also

C x.x.x.2/32 is directly connected, MultilinkXX

in the list.

Why the connected route with 32-bit network is in the list?

Correct Answer by royalblues about 8 years 7 months ago

When you use PPP encapsulation, IOS by default would install a /32 route in the RT

To remove this route use the command under the interface

no peer neighbor-route
