Topology:
Requirements:
At
the end of this task, any router loopback interface should have
connectivity to any other router loopback in the topology.
Only
use ISIS routing protocol. No other protocols, including static
routing are allowed.
R1
and R4 should be configured in ISIS area 49.0013.
R3
should be configured in ISIS area 49.0004.
Configure
R2 to allow full connectivity between all devices in the topology
Solution:
The
solution is to configure R2 for ISIS Multihoming. Multihoming allows
merging two ISIS areas into single area, by configuring multiple NET
values under same ISIS process. Note that System-ID should be
identical.
R2:
