Subject: [c-nsp] load balance between to EBGP peers

Hi all ,

i have MPLS/VPN network based on 7600's . all the Internet is going via
VRF-INTERNET , my ASBR gets full route from 2 peers via OC12 POS
interfaces
on VRF INTERNET  , also he gets 0.0.0.0 route from both peers but of
course
only 1 gets to FIB .
my target is to get load balance between the 2 peers(on the ASBR) in the
outgoing traffic and to redistribute only 0.0.0.0 to VRF INTERNET to all
the
IBGP peers.  what i see now is  that the 0.0.0.0 gets label in the FIB
of
the ASBR pointing on one of the POS interface, so the other POS stay
empty , with the show ip route vrf INTERNET 0.0.0.0 0.0.0.0 command i
see
the LB0 of the ASBR which is OK but the MPLS label table on the VRF
INTERNET
is pointing on the POS interface . i just want that the ASBR will route
the
traffic according to his full route table .

so actually now i redistribute to all PE's /20 subnets for getting load
balance ,
does someone have a good ides for this one ?

regards moshe
