Opened: Mar 06, 2018

Severity: 2-Critical


Route entries for IPv4-mapped IPv6 address (::ffff:<IPv4>) are not created in TMM when passed from Dynamic Routing protocols like OSPFv3.


- Route entry is not created in TMM, packets addressed to such a destination might not be delivered at all or might not be delivered using the most efficient route. - Connection between TMM and tmrouted is restarted that is a small performance overhead.


- Route entry is for IPv4-mapped IPv6 address, that is ::ffff:<IPv4>.


- If possible IPv4 address or IPv4-compatible IPv6 address should be passed instead of IPv4-mapped IPv6 address, however this depends on other routers.
