Hi,
Not only you have to configure 'bgp bestpath as-path ignore' but also
'maximum-paths 2'. The latter if used in iBGP, will only be available
from 12.2S. 12.2S is not out yet. In your case should work since it is
eBGP... And multipath support is available for eBGP since 11.3 If I
remember correctly.
It's worth a try in the lab... I guess if you adjust the metrics
accordingly (to make them all equal) and ignore the AS_PATH attr, then
it should work nicely...
Good question!
Cheers,
