Sorry for any duplication, but not everyone is on bgpd. --Steve Widmayer / Merit *********************************************************************** Date: Sun, 20 Feb 94 23:25:31 EST From: Jordan Becker <becker@ans.net> To: bgpd@merit.edu Subject: Feb 20th AS690 Gated/BGP4 Deployment 1. Gated / Rcp_routed Activities for Sunday Feb 20th 00:30 EST ---------------------------------------------------------------- We did some further gated/BGP4 deployment on AS690 routers this past Sunday morning at 00:30EST. We are now running gated on 22 AS690 routers. The following progress was made: 1.1 Increased kernel paging space to 96MB on ENSS137, ENSS138, ENSS144, ENSS145. 1.2 Reconfigured gated nodes (ENSS160, ENSS205, CNSS105) to add the 127.0.0.1 loopback address. This allows gated to handle reject routes correctly so that no default is triggered on AS690 routers for unreachable 140.222 destinations. We will burn this in for a couple of days and add the loopback interface to other gated systems during the Tuesday March 1st. configuration window. 1.3 Deployed gated version ANS0.5 on nodes already running gated (version ANS0.4) including: ENSS205, ENSS194, ENSS160, CNSS104, CNSS107, ENSS158, ENSS120. This version of gated fixes memory leak during reconfiguration, and the SLSP LSP max. aging problem. 1.4 Deployed the new gated (ANS0.5) to replace rcp_routed on AS690 nodes including: ENSS131, ENSS139, CNSS105, ENSS138, ENSS132, ENSS186, ENSS213, ENSS222, ENSS224, CNSS72, CNSS75, ENSS150, ENSS151. 1.5 Deployed new gated (ANS0.5o) on ENSS136. This gated has optimization turned on. 1.6 Reconfigured gated (ANS0.5) on ENSS136 multiple times to ensure that dynamic reconfiguration works without memory leaks. 2. Points of Interest to Users ================================ 2.1 Because AS690 is running with default, users that try to traceroute nets that are unreachable nets over AS690 will get a path to Washington2.Dante.net (AS1133). This makes debugging a bit more difficult while AS690 runs with a default route. 2.2 Gated is running on AS690 with BGP version negotiation enabled. This allows external peers to negotiate up to the highest version level of BGP that their peer is configured to support. Some peers may already be configured to version negotiate from BGP2->BGP3 which may happen automatically with the AS690 gated deployment. Peer service providers should check their configurations for this to ensure that there are no unexpected problems. 3. New Problems Identified - Sunday Feb. 20th =============================================== 3.1 Gated (0.5) has a problem in gated SLSP where the dummy AS (required for rcp_routed multi-homed AS's) does not get passed on from gated -> rcp_routed systems correctly. We saw problems with dummy AS numbers including AS291, AS702, AS60, AS201, AS2884. This caused us to back out gated on ENSS144, ENSS134 where these dummy AS numbers are used. We will fix this problem and plan to re-deploy on ENSS144, ENSS134 on Tuesday morning March 1st. 3.2 Gated does not handle statically announced multiple external nets correctly. Gated does handle the case where the single DMZ net is statically announced to AS690 (ENSS186, ENSS213, ENSS224). Because Gated could not announce multiple statics we left rcp_routed running on ENSS164, ENSS222. 4. Tuesday morning March 1 05:00EST Scheduled Maintenance ----------------------------------------------------------- 4.1 Configure 127.0.0.1 loopback interface on all gated nodes *EXCEPT* those that already support it (ENSS205, ENSS160, ENSS194). 4.2 Gated re-starts on the following gated nodes already running gated including: ENSS205, ENSS194, ENSS160, ENSS131, ENSS139, CNSS104, CNSS105, CNSS107, ENSS136, ENSS138, CNSS120, ENSS158, ENSS136, ENSS132, ENSS186, ENSS213, ENSS224, CNSS72, CNSS75, ENSS150, ENSS151. 4.3 Deploy new gated (ANS0.6) to replace rcp_routed on nodes including: CNSS88, CNSS91, ENSS134, ENSS144, ENSS143, ENSS176, ENSS193, ENSS222, ENSS226, ENSS230. This version of gated (ANS0.6) fixes the SLSP handling of dummy AS numbers, and static announcement of multiple external nets. *********************************************************************** Date: Mon, 21 Feb 94 0:23:58 EST From: Jordan Becker <becker@ans.net> Subject: Re: Feb 20th AS690 Gated/BGP4 Deployment To: bgpd@merit.edu
