OSPFv3 doesn't support decimal area syntax
Closed, ResolvedPublicBUG
Actions

Description

Config commit fails when using u32 integer area notation in OSPFv3.

ospfd allows area notation of type u32 integer or ipv4.
ospf6d allows area notation of only ipv4.

If I run

delete protocols ospfv3
set protocols ospfv3 area 0.0.0.0 interface eth0
commit

everything works as expected.

If I run

delete protocols ospfv3
set protocols ospfv3 area 0 interface eth0
commit

the commit fails with % Unknown command: interface eth0 area 0.

Need to remove u32 integer from the OSPFv3 area input template.

Change validator type for ospv3 area
FRR supports the only x.x.x.x value for interface area

r1-roll(config-ospf6)# interface eth1 area 
  A.B.C.D  OSPF6 area ID in IPv4 address notation
vyos@r1-roll# set protocols ospfv3 area 0 interface eth1

  "0" is not a valid value of type "ipv4"
  Value validation failed
  Set failed

[edit]
vyos@r1-roll# set protocols ospfv3 area 1 interface eth1

  "1" is not a valid value of type "ipv4"
  Value validation failed
  Set failed

[edit]
vyos@r1-roll# set protocols ospfv3 area 0.0.0.0 interface eth1
