2024-11-19bgpd: Disable sending ROV extended community by defaultDonatas Abraitis
https://datatracker.ietf.org/doc/html/rfc8097 defines ROV extended community, but https://datatracker.ietf.org/doc/draft-ietf-sidrops-avoid-rpki-state-in-bgp is against sending it by default even for iBGP peers. Let's do this practice and reverse it. Signed-off-by: Donatas Abraitis <donatas@opensourcerouting.org>

2024-09-02bgpd: Do not scan update-groups if default-originate timer is set to 0Donatas Abraitis
With lots of update-groups, subgroups, this could be very tricky and the timer is spawned even if it's totally unnecessary (default-originate is not enabled). Signed-off-by: Donatas Abraitis <donatas@opensourcerouting.org>

2024-07-04bgpd: Implement `neighbor X remote-as auto`Donatas Abraitis
In some cases (large scale) it's desired to avoid changing configurations, but let the BGP to automatically handle ASN changes. `auto` means the peering can be iBGP or eBGP. It will be automatically detected and adjusted from the OPEN message. Signed-off-by: Donatas Abraitis <donatas@opensourcerouting.org>
2024-07-01*: Add and use option for graceful (re)startvivek
Add a new start option "-K" to libfrr to denote a graceful start, and use it in zebra and bgpd. zebra will use this option to denote a planned FRR graceful restart (supporting only bgpd currently) to wait for a route sync completion from bgpd before cleaning up old stale routes from the FIB. An optional timer provides an upper-bounds for this cleanup. bgpd will use this option to denote either a planned FRR graceful restart or a bgpd-only graceful restart, and this will drive the BGP GR restarting router procedures.

2024-06-02bgpd: Adjust terminology related to DSCPDavid Ward
The default DSCP used for BGP connections is CS6. The DSCP value is not part of the TCP header. When setting the IP_TOS or IPV6_TCLASS socket options, the argument is not the 6-bit DSCP value, but an 8-bit value for the former IPv4 Type of Service field or IPv6 Traffic Class field, respectively. Fixes: 425bd64be847 ("bgpd: Allow bgp to control the DSCP session TOS value") Signed-off-by: David Ward <david.ward@ll.mit.edu>

2024-01-07bgpd: Add `debug bgp updates detail` commandDonatas Abraitis
When filtering with `debug bgp updates in x.x.x.x prefix-list plist`, we want to filter out unnecessary messages like: ``` 127.0.0.1(Unknown) rcvd UPDATE wlen 0 attrlen 20 alen 5 ``` Such a line as above will be repeated for all the paths received and it's useless without knowing the prefix (because NLRIs are not parsed yet). But want to see only relevant ones: ``` 127.0.0.1(Unknown) rcvd UPDATE w/ attr: nexthop 127.0.0.1, origin i, path 65002 127.0.0.1(Unknown) rcvd 10.255.255.1/32 IPv4 unicast ``` With `debug bgp updates detail` we can combine this to something like: ``` 127.0.0.1(Unknown) rcvd UPDATE w/ attr: nexthop 127.0.0.1, origin i, path 65002 127.0.0.1(Unknown) rcvd UPDATE wlen 0 attrlen 20 alen 5 127.0.0.1(Unknown) rcvd 10.255.255.1/32 IPv4 unicast ``` Signed-off-by: Donatas Abraitis <donatas@opensourcerouting.org>
