Hi all. I want to install FRR 8.2.2 release from source code for ospfd running on CenOS 7. So, I followed the guide line from http://docs.frrouting.org/projects/dev-guide/en/latest/building-frr-for-cent os7.html. - First, when I run: ./configure --bindir=/usr/bin --sbindir=/usr/lib/frr --sysconfdir=/etc/frr --libdir=/usr/lib/frr --libexecdir=/usr/lib/frr --localstatedir=/var/run/frr --with-moduledir=/usr/lib/frr/modules --enable-snmp=agentx --enable-multipath=64 --enable-user=frr --enable-group=frr --enable-vty-group=frrvty --disable-ldpd --enable-fpm --with-pkg-git-version --with-pkg-extra-version=-MyOwnFRRVersion SPHINXBUILD=/usr/bin/sphinx-build I got two warnings: configure: WARNING: sphinx is missing but required to build documentation configure: WARNING: pytest is missing, unit tests cannot be performed - After compile source and install I run sudo systemctl start frr I got error message like below: [root@localhost frr]# sudo systemctl start frr Job for frr.service failed.

Question about BGP NLRI structure
by johnjdunbar＠disroot.org 11 Jun '22

11 Jun '22

I'm trying to implement https://datatracker.ietf.org/doc/draft-ietf-idr-sdwan-edge-discovery/ into frr/bgpd. Looking through the code I have some questions for which I hope someone can help me RFC 4760 defines the mp_reach_nlri attributes as this +---------------------------------------------------------+ | Address Family Identifier (2 octets) | +---------------------------------------------------------+ | Subsequent Address Family Identifier (1 octet) | +---------------------------------------------------------+ | Length of Next Hop Network Address (1 octet) | +---------------------------------------------------------+ | Network Address of Next Hop (variable) | +---------------------------------------------------------+ | Reserved (1 octet) | +---------------------------------------------------------+ | Network Layer Reachability Information (variable) | +---------------------------------------------------------+ Is the following structure in /bgpd/bgpd.h representing the table above? struct bgp_nlri { /* AFI. */ uint16_t afi; /* iana_afi_t */ /* SAFI. */ uint8_t safi; /* iana_safi_t */ /* Pointer to NLRI byte stream. */ uint8_t *nlri; /* Length of whole NLRI. */ bgp_size_t length; }; If yes, does uint8_t *nlri map to [Network Layer Reachability Information (variable)]? does bgp_size_t length map to [Length of Next Hop Network Address (1 octet)]? If not, can someone please tell me what this structure maps to? I appreciate anyone who has insights to help me out. Thank you, John
