Hello!
ASR CISCO<--->X460<--->X670/1<--->X8<--->X670/2<--->Second Router
ND isn’t forwarded between ASR and other end Router, feelings that multicast is somewhere lost.
IPv6 configured on Routers.
EXOS switches as transit nodes (no neighbors, no cache) - only forward traffic in 1 VLAN.
EXOS versions is 16.2.5.4-patch1-5
Ping from X8 to both X670 work fine.
Ping from X8 to X460 doesn’t work.
X8# ping 2222:6d5:4f::1
Ping(ICMP6) 2222:6d5:4f::1: 4 packets, 8 data bytes, interval 1 second(s).
--- 2222:6d5:4f::1 ping statistics ---
4 packets transmitted, 0 packets received, 100% loss round-trip min/avg/max = 0/0/0 ms
Outbound packets go out from X8 to X460, from X460 to X8 - no.
If made ACL on X670 as ingress (from X460):
entry any_v6 {
if {
source-address 0:: / 0;
}
then {
log;
mirror-cpu;
count ND;
permit;
}
}

If configure same ACL on X8 on ingress (from X670) - there is no packets.
Any ideas?
Thank you!
