Hello MikroTik forums,

I've been playing with MikroTik's CHR-6.36.3 images in GNS3 to simulate a dual-stack network. However, it seems like the software's IPv6 route recursive lookups are broken.

[admin@chr-1] > ipv6 route print terse where dst-address=2001:10::2/128
0 ADo dst-address=2001:10::2/128 gateway=fe80::2f7:aff:fe13:f600%ether1 gateway-status=fe80::2f7:aff:fe13:f600%ether1 reachable distance=110 scope=20 target-scope=10 ospf-metric=10

[admin@chr-1] > ipv6 route print terse where dst-address=2001:20::/32
0 Db dst-address=2001:20::/32 gateway=2001:10::2 gateway-status=2001:10::2 unreachable distance=200 scope=40 target-scope=30 bgp-as-path=20 bgp-local-pref=100 bgp-origin=igp received-from=iBGP-v6-chr-2

From the IPv6 routing table, 2001:10::2/128 is clearly an active route. However, prefix 2001:20::/32, which is pointing towards 2001:10::2, is deemed to be unreachable.

How is this so?
