[j-nsp] How does multihop eBGP work?

[Doug Hanks]

Mike,

By default ebgp sends packets with a ttl=1.  When you enable multihop you can override the default and set "multihop 5" for example.

Thank you,

Hey guys,

I've got a situation I think I need multihop bgp for (logical-systems and 
bridge-domains).
However it bugs me deeply that I don't "get" multihop BGP.

My biggest bugbear is if my multihop-ebgp peer tells me he know the best way 
to x.x.x.x, the packets I send towards him must be routed by intermediaries, 
will those intermediaries use their tables and "hijack" my packets down their 
bits of wet string through 15 other ASs and to the moon and back?

Thanks
