R1 is able to reach only some of the subnets that R2 is advertising. Which two configuration changes
can you make to ensure that R1 can reach all routes from R2? (Choose two.)
A.
Add an additional permit statement to the LOOPBACKS route map.
B.
Modify the LOOPBACKS access list to include all loopback subnets.
C.
Add an additional statement in the LOOPBACKS route map to match both Level 1 and Level 2
circuits.
D.
Add an additional statement in the LOOPBACKS route map to match the R1 CLNS address.
E.
Configure the interfaces between R1 and R2 with a Level 1 IS-IS circuit.
F.
Configure the interfaces between R1 and R2 with a Level 2 IS-IS circuit.
In this example, the access list is using a 0.0.3.255 wildcard mask, so only the loopback IP’s of
172.16.0.0 – 172.16.3.255 will be included. We need to add another statement to allow loopback 4
to be advertised, or modify the wildcard mask to include them all.
