From de842255f9a1930d7f927e94e7ea800bcfd1434c Mon Sep 17 00:00:00 2001
From: Patrick Ruddy <pruddy@vyatta.att-mail.com>

Subject: [PATCH] ospf6d: decimal area format in interface command
The ospf6 "interface <blah> area <x>" command only allows the area to
be specified in the ipv4 address format, whereas the show run command
always shows it in the format in which the area was created. This causes
the frr-reload script to be unable to remove ospfv3 interfaces when the
area was created in decimal format. The solution is to allow both formats
to be configured as they can be for other area commands.
