Hi,
Is it foolish to build a L3 ECMP connection between 2 iBGP routers with one=
of the links having a 50% longer RTT? We're building fiber between 2 locat=
ions with the option of going both north and south around the great lakes. =
One link will have a 20ms RTT and one with around 35ms. The majority of our=
peering and transit will be on one side, with the enterprise datacenter on=
the other.
The design right now would use OSPF as an IGP over these links with iBGP pe=
ering on loopbacks. Both links are 1G.
Any thoughts on doing this different/better would be appreciated.
Thanks.
