The default IS-IS network type is point-to-point so a DIS is not elected

A DIS is elected between the IS-IS neighbors and the elected DIS is pre-empted if router with a higher system ID is connected

The area, levels, and interface MTU parameters must match, and system MTU must be unique for two IS-IS routers to become adjacent

Faster IS-IS hello and dead timers increase bandwidth and CPU use, and may cause instability

The IS-IS hello and dead timers should be tuned to detect failures as quickly as possible

A DIS is elected between the IS-IS neighbors and the elected Dis is pre-empted if a router with a lower system ID is connected

The hello and dead timers must match for two IS-IS routers to become adjacent

Two REP segments can be connected redundantly at two points, one connection will be blocked as per the STP defined in IEEE 802.1d.

UDLD can be enabled on REP interfaces to detect unidirectional failures.

The guaranteed convergence recovery time is less than 50 ms for the local segment.

A REP segment is limited to a maximum of seven devices.

VLAN load balancing for optimal bandwidth usage is supported in any REP segment.

It provides backup convergence for all topologies by avoiding the post-convergence path

It maximizes the network utilization by load-sharing across low bandwidth and edge links while IGP convergence is in progress

No additional protocols are required in the MPLS network because it uses LDP labels to signal the backup path

Although it requires enabling segment routing, SR does not have to be activated as the preferred forwarding method

It can provide backup paths for IPv4, IPv6 and LDP traffic
