[c-nsp] Two Cores connected to same eBGP AS

[Chris Knipe]

Hi,

I have a quick question...   Let's say I have RTR1 and RTR2
interconnected and exchanging routes via EIGRP, on AS abc

I now want to connect AS abc from RTR1 as well as RTR2 to AS xyz and
broadcast my ranges to them, and receive routes from them.

Is it safe to just connect both sessions and let the traffic route via
RTR1 as well as RTR2, or, considering RTR2 is for a failover scenario,
how would one automatically achieve a Active/Passive failover scenario
so that RTR2 will only establish the BGP session when RTR1 is down /
inaccessible / etc?

Sorry if this is something very common, or very complex - I'm more
than willing to do some reading up if there can be pointers given
please.

Both RTR1 and 2 are 6500 series - the amount of routes exchanged will
be minimal < 100K prefixes.
