Can a loopback interface ...

Can a loopback interface be added to both OSPF and IS-IS?

Hi all,

Brief topology: R1---(ISIS)---R2---(OSPF)---R3

As shown in the preceding command output, IS-IS runs between R1 and R2, and OSPF runs between R2 and R3. Therefore, the loopback interface on R2 can be added to both OSPF and IS-IS. After the preceding configurations, R1 and R3 can learn the loopback address of R2 through the protocols.

I do not want R1 and R3 to communicate with each other. Is there any problem with the configuration?

Thank you.

Hi Sprout,

The configuration is not affected. OSPF and IS-IS are still two separate IGP areas. R1 can communicate with R3 only after routes are imported between the two areas on R2.
