Hi, I'm using frr version 4.0+cl3u17 on a Cumulus router. I'm having troubles setting the managed-config-flag for RA packets. I have this in my configuration file for the VLAN interface I'd like to configure with the managed-config-flag on: | interface vlan124 | vrrp 3 | vrrp 3 ipv6 fd00:4d56:414c:6000::1 | vrrp 3 priority 150 | ipv6 nd managed-config-flag But when I sniff the outgoing packets on the interface, I get "Flags [none]" in tcpdump: | # tcpdump -lnn -i vlan124 -vvvv -ttt icmp6 and 'ip6[40] = 134' | tcpdump: listening on vlan124, link-type EN10MB (Ethernet), capture size 262144 bytes | 00:00:00.000000 IP6 (hlim 255, next-header ICMPv6 (58) payload length: 24) fe80::c981:f4f7:7f26:a79b > ff02::1: [icmp6 sum ok] ICMP6, router advertisement, length 24 | hop limit 64, Flags [none], pref medium, router lifetime 48s, reachable time 0ms, retrans timer 0ms | source link-address option (1), length 8 (1): 00:00:5e:00:02:03 | 0x0000: 0000 5e00 0203 Is there something I'm doing wrong? Any help is appreciated. Thanks, Thomas
