[c-nsp] Load Balancing

[A. Rahman Isnaini R Sutan]

Sorry, yes for link state.
For distance vector similar prefixes appear on the database.

This currious raised up once I configure OSPF for redundancy.
So my router didn't show similar routes with different OSPF "attribute" but
only one route.
Once other link changed state to down, the other similar OSPF routing
appears immediately.

Hmm, not really.. for link-state we can display the LSA/LSP's and part
of the tree (i.e. "show isis topology"). BGP as a path-vector protocol
works so much differently than link-state that outputs like "I received
these routes with these metrics from these neighbors" don't really
apply.
For RIP as a distance-vector protocol, you can do "show ip rip database"
which shows "similar" information, EIGRP as well ("show ip eigrp
topology")
