>From RFC4271: 4. Message Formats This section describes message formats used by BGP. BGP messages are sent over TCP connections. A message is processed only after it is entirely received. The maximum message size is 4096 octets. All implementations are required to support this maximum message size. The smallest message that may be sent consists of a BGP header without a data portion (19 octets). I suppose JUNOS lets it use an MSS of Nx4096 that will fit in the PMTU. Then again, there was a long standing bug that shows 2x whatever the actual MSS was on show system connections output too, so who knows. :) But under "protocols bgp neighbor x.x.x.x tcp-mss" the maximum value you can specify if you aren't doing automatic PMTUD is 4096, go figure. -- Richard A Steenbergen <r...@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC) _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
