The update to *26.02* brought along many changes that I can’t find documented anywhere; unfortunately, it’s not a usable version for me. Upgrading from *25.10* to *26.02* causes several things to stop working.
In addition to what has already been reported, the current issue is that traffic between two instances (VM = Debian + VPP + FRR) cannot be established from the Linux side, though it works from VPP. For example, if I ping from Linux to the other instance, it fails; if I ping from VPP, it works. Consequently, services (such as BGP) are not functioning. > > core-vpp:~# ip vrf exec interno ping 10.10.10.5 -c 1 > PING 10.10.10.5 (10.10.10.5) 56(84) bytes of data. > --- 10.10.10.5 ping statistics --- > 1 packets transmitted, 0 received, 100% packet loss, time 0ms > core-vpp:~# vppctl > _______ _ _ _____ ___ > __/ __/ _ \ (_)__ | | / / _ \/ _ \ > _/ _// // / / / _ \ | |/ / ___/ ___/ > /_/ /____(_)_/\___/ |___/_/ /_/ > vpp# ping 10.10.10.5 source ens16.3001 repeat 1 > 116 bytes from 10.10.10.5: icmp_seq=1 ttl=64 time=7.2317 ms > Statistics: 1 sent, 1 received, 0% packet loss > vpp# quit > core-vpp:~# ip add show dev ens16.3001 > 5: ens16.3001@ens16: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc > noqueue master interno state UP group default qlen 1000 > link/ether 44:4c:a8:20:99:aa brd ff:ff:ff:ff:ff:ff > inet 10.10.10.6/30 scope global ens16.3001 > valid_lft forever preferred_lft forever > inet6 fc00::10:10:10:6/126 scope global > valid_lft forever preferred_lft forever > inet6 fe80::464c:a8ff:fe20:99aa/64 scope link > valid_lft forever preferred_lft forever > core-vpp:~# ip neighbo show dev ens16.3001 > 10.10.10.5 lladdr 44:4c:a8:20:88:9e STALE > fc00::10:10:10:5 lladdr 44:4c:a8:20:88:9e REACHABLE > If I perform a downgrade, everything goes back to working normally. > > apt install vpp=25.10-release libvppinfra=25.10-release > vpp-plugin-core=25.10-release vpp-plugin-dpdk=25.10-release > python3-vpp-api=25.10-release >
