Asymmetric routing with tunnel.

Mon Mar 30 22:56:20 UTC 1998

I can provide details ..

We are using a 45M satellite circuit operating from Teleglobe
to Telstra. The circuit is configured as a unidirectional
circuit with no direct return path. 

We use BGP as the link keepalive protocol as well as the
route peering protocol, using the two lookpack addresses
as the peering points for the BGP TCP session. The circuit
is now operating in production mode successfully.

A description of the initial test rig including template
router configs can be found at http://www.telstra.net/ops/unid. 

The work was undertaken with the support of Telstra, Teleglobe
and Intelsat.

Thanks,

  Geoff Huston
