[c-nsp] BGP timer selection with DISA

[Chuck Church]

Anyone,

	Looking at adjusting our BGP neighbor keepalive/dead timers for
connection to DISA.  Our standard site config is 2 edge routers, each with a
DISA circuit/peer and iBGP between the two routers of ours.  What are
sensible timer settings for our environment?  Our router CPUs tend to run
pretty low (even though they are Sup720 and ISR or ISR G2 at small sites -
under 20%) and circuits tend to average fairly low utilization (under 50%)
over long periods.  Full DISA table is under 20,000 prefixes, so I don't
anticipate CPU issues during neighbor establishment.  Was thinking 5/20 for
DISA eBGP peers, and 3/12 for iBGP between our two.  Too aggressive?

Thanks,

Chuck Church
