Hi, looks like Junos allows to have only a single IPv6 link-local address. For example, here I tested with Junos 18.2R1.9:
root@vmx1# show | compare [edit interfaces ge-0/0/9 unit 0 family inet6] address fe80::206:aff:fe0e:fffa/64 { ... } + address fe80:1::206:aff:fe0e:fffa/64; [edit] root@vmx1# commit check [edit interfaces ge-0/0/9 unit 0 family inet6] 'address fe80:1::206:aff:fe0e:fffa/64' Link Local address exists error: configuration check-out failed [edit] root@vmx1# ..or: root@vmx1# show | compare [edit interfaces ge-0/0/9 unit 0 family inet6] address fe80::206:aff:fe0e:fffa/64 { ... } + address fe80::206:aff:fe0e:fffb/64; [edit] root@vmx1# commit check [edit interfaces ge-0/0/9 unit 0 family inet6] 'address fe80::206:aff:fe0e:fffb/64' Link Local address exists error: configuration check-out failed [edit] root@vmx1# Just out of curiosity, why there is this limitation? For example FreeBSD 11, which Junos 18.2R1.9 is based on, does not have this limitation: root@FreeBSD-11:~ # ifconfig em0 inet6 em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=209b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_MAGIC> inet6 fe80::fc69:d3ff:feec:7741%em0 prefixlen 64 scopeid 0x1 inet6 fe80::fc69:d3ff:feec:7740%em0 prefixlen 64 scopeid 0x1 nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL> root@FreeBSD-11:~ # thanks, Martin _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
