Re: Active Router Advertissement IPV6 SRX : repond ping: sendmsg: No route to host

Hi !

Find here a working example of IPv6 RA including 2 VRRP groups for IPv6 (address changed)

interfaces {

ge-0/0/6 {
unit 0 {
family inet {
address 1.123.226.1/25 {
vrrp-group 26 {
virtual-address 1.123.226.100;
priority 250;
preempt {
hold-time 60;
}
accept-data;
}
}
address 1.123.225.2/25 {
vrrp-group 25 {
virtual-address 1.123.225.100;
preempt {
hold-time 60;
}
accept-data;
}
}
}
family inet6 {
address aaaa:e380:8111::2/48 {
vrrp-inet6-group 125 {
virtual-inet6-address aaaa:e380:8111::100;
virtual-link-local-address fe80::8111:100;
preempt {
hold-time 60;
}
accept-data;
}
}
address fe80::8111:2/64;
address aaaa:e380:8222::2/48 {
vrrp-inet6-group 126 {
virtual-inet6-address aaaa:e380:8222::100;
virtual-link-local-address fe80::8111:200;
priority 250;
preempt {
hold-time 60;
}
accept-data;
}}}}}}

Note that you can only have one link local address on the interface and one link local VIP per vrrp group

###################### here the normal Router advertisment with SLAAC #######################

protocols {
router-advertisement {
interface ge-0/0/6.0 {
max-advertisement-interval 4;
virtual-router-only;
prefix aaaa:e380:8111::/48;
prefix aaaa:e380:8222::/48;
}
}

######################### here the RA if you do NOT want SLAAC  ###################

protocols {
router-advertisement {
interface ge-0/0/5.0 {
max-advertisement-interval 4;
virtual-router-only;                                     
prefix aaaa:e380:8111::/48 {
no-on-link;
no-autonomous;
}
prefix aaaa:e380:8222::/48 {
no-on-link;
no-autonomous;
}
}
}

the virtual-router only statement means that only the VRRP master is sending out the RA

Hope that helps

regards
