I have two vMX routers with GRE connection.
set logical-systems SRX3 interfaces gr-0/0/10 unit 0 tunnel source 172.30.15.3
set logical-systems SRX3 interfaces gr-0/0/10 unit 0 tunnel destination 172.30.15.1
set logical-systems SRX3 interfaces gr-0/0/10 unit 0 family inet address 172.30.0.130/30set logical-systems SRX3 interfaces gr-0/0/10 unit 0 family inet6 address fd17:f0f4:f691:3::6/126
set interfaces gr-0/0/10 unit 0 tunnel source 172.30.15.1
set interfaces gr-0/0/10 unit 0 tunnel destination 172.30.15.3
set interfaces gr-0/0/10 unit 0 family inet address 172.30.0.129/30set interfaces gr-0/0/10 unit 0 family inet6 address fd17:f0f4:f691:3::5/126
GRE works fine.
On both routers, I have ospf3 configurations as follows:
root@SRX1-ISP1# show | display set | match ospf3 | match gr-0/0
set protocols ospf3 realm ipv4-unicast area 0.0.0.3 interface gr-0/0/10.0 interface-type p2p
set protocols ospf3 area 0.0.0.3 interface gr-0/0/10.0 interface-type p2p
root@SRX3-SRX4# show logical-systems | display set | match ospf3 | match gr-0/0
set logical-systems SRX3 protocols ospf3 realm ipv4-unicast area 0.0.0.3 interface gr-0/0/10.0 interface-type p2p
set logical-systems SRX3 protocols ospf3 area 0.0.0.3 interface gr-0/0/10.0 interface-type p2p
I got the following from traceoptions:

I noticed both link-local addresses are the same. Do you think I need to manually configure link-local address on gre itnerfaces ?
thanks in advance !!!
