So we all know that static routing presumably does "equal cost" load balancing for traffic (since static routes are only up until the next hop this equal cost label is somewhat moot). What I'd like to know is how redistributing static routes to the same destination get injected into OSPF...because if what I'm going by is any indication, it would appear only one route seems to get installed in the routing table irrespective of the number of static routes configured going to a single destination.
For instance, lets assume we have network 10.0.0.0/24. We have two static routes going to said network, one via interface Serial1 and the other via interface Serial2 like so:
ip route 10.0.0.0 255.255.255.0 Serial1
ip route 10.0.0.0 255.255.255.0 Serial2
When you run "show ip route | inc 10.0.0.0" from some point on the network, you'd presumably get :
rtrA#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate default
U - per-user static route, o - ODR
E2 10.0.0.0 via .... (whatever the Forward Path next hop is)
So basically the route gets installed once...or so it would appear. Sorry not at work at the moment so can't copy/paste the exact output but its something to that effect.
Is this behavior normal ? What do the powers that be say over the same ?
