4Byte to 2Byte ASN conversion issue for BGP community
nitesh058 opened this issue · comments
Hi Barryo,
Please help for N:M filtering based on standard community strings. As standard or Large BGP communities support only 2
bytes, How we map peer asn with 2-byte private ASN as per below-mentioned table in a routeserver, so that we can provide a 2-byte private ASN to our other Peers who have 4-byte ASN, to apply community accordingly.
Peer 32-bit | ASN | BGP Community
Peer1 | 133469 | 65000
Peer2 | 132570 | 65001
Peer3 | 133168 | 65002
Please give the solution and thanks in advance..
you need to use bgp large communities for this, as they were designed to support 4-byte asns.
@nitesh058 - see https://docs.ixpmanager.org/features/route-servers/#well-known-filtering-communities for large communities.
As @nickhilliard, you'll need to use large communities.
As an alternative, we'll shortly be releasing a new version of IXP Manager which will allow community filtering to be enabled on the route server side of the BGP peering via a UI in IXP Manager - meaning no configuration required on member routers.
Problem 1
- Installation request for doctrine/dbal 3.6.0 -> satisfiable by doctrine/dbal[3.6.0].
- doctrine/dbal 3.6.0 requires composer-runtime-api ^2 -> no matching package found.
Potential causes:
- A typo in the package name
- The package is not available in a stable-enough version according to your minimum-stability setting
see https://getcomposer.org/doc/04-schema.md#minimum-stability for more details. - It's a private package and you forgot to add a custom repository to find it
Getting composer error, even we have tried to install the composer and doctrine/dbal before run ixpmanager automated install script, please help how to fix this.
Hi @nitesh058 - just a matter of good practice, please don't reply to closed tickets for new issues. This is also not a bug so it's really a query for the mailing list.
That said - looks like you're running an old version of composer. You need composer >= v2. See https://getcomposer.org/
