is the 'bandwidth' of the bgp protocol in the wire an actual concern? (at some point the discussion point came up ~1yr or more ago, but was discarded as not relevant given circuit sizes and bandwidth from link -> RP/RE/etc, so I'm genuinely curious about this) > > Anyway, I guess I was mostly just curious about what kinds of evaluations > have been done, thanks. :) > > Eric > > On Nov 8, 2011, at 12:19 PM, Sriram, Kotikalapudi wrote: > >> Now the ops doc has much longer beaconing interval recommendations >> for what you may consider a normal prefix. >> >> http://tools.ietf.org/html/draft-ietf-sidr-bgpsec-ops-01#section-7 >> >> Normal Prefix: Most prefixes SHOULD announce with a signature >> validity of a week and beacon every three days. >> >> Sriram >> >> -----Original Message----- >> From: Jakob Heitz [mailto:[email protected]] >> Sent: Tuesday, November 08, 2011 12:09 PM >> To: Sriram, Kotikalapudi >> Cc: Christopher Morrow; Eric Osterweil; sidr wg list >> Subject: Re: [sidr] WGLC: draft-ietf-sidr-bgpsec-reqs >> >> Proposal was 24 hour beacon timeout and 3 beacons per timeout.
