Default EBGP/IBGP Load Balancing

Hi All,

Is it possible to install a routes into routing table from the same subnet coming from two different sources ebgp/ibgp and "load balance" the traffic? I've searched the forums found threads similar to my question but there was never a clear answer if it was possible or not.

i've used the lines below to tweak ad/weight/lp etc...

RTRA

router bgp 100
no synchronization
bgp log-neighbor-changes
bgp bestpath as-path multipath-relax
neighbor 1.1.1.2 remote-as 100
neighbor 1.1.1.2 next-hop-self
neighbor 1.1.1.2 soft-reconfiguration inbound
neighbor 1.1.1.2 route-map bgp in
neighbor 2.2.2.2 remote-as 200
neighbor 2.2.2.2 soft-reconfiguration inbound
neighbor 2.2.2.2 route-map bgp in
maximum-paths 2
maximum-paths ibgp 2
distance 200 2.2.2.0 0.0.0.3
no auto-summary

route-map bgp permit 10
set metric 0
set local-preference 100
