Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. ovn-nbctl ls-add sw0
    ovn-nbctl set logical_switch sw0:other_config:ipv6_prefix="aef0::/64"
    ovn-nbctl lsp-add sw0 sw0-p1 -- lsp-set-addresses "00:00:00:00:20:01 dynamic"
2.
3.

Actual results:

Address assignment to sw0-p1 fails.


Expected results:
Address assignment to sw0-p1 should be successful.
