Configure stub areas
Configure Passive-Interface
Use the following command to suppress the interface’s participation on an OSPFv3 interface. This
command stops the router from sending updates on that interface.
To enable both receiving and sending routing updates, enter the no passive-interface interface
command.
When you configure a passive interface, the
show ipv6 ospf interface command adds the words
“passive interface” to indicate that hello packets are not transmitted on that interface.

[no-summary]
CONF-IPV6-ROUTER-OSPF Configure the area as a stub area. Use the no-summary
keywords to prevent transmission in to the area of summary
ASBR LSAs.
Area ID is a number or IP address assigned when creating the
Area.
The Area ID can be represented as a number between 0 –
65536 if a dotted decimal format is assigned, rather than an
IP address.

Interface identifies the specific interface that will be passive.
• For a Gigabit Ethernet interface, enter the keyword
GigabitEthernet followed by the slot/port information
(e.g. passive-interface gi 2/1).
• For a port channel, enter the keyword port-channel
followed by a number from 1 to 255 for TeraScale and
ExaScale (e.g. passive-interface po 100)
• For a 10-Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet followed by the slot/port
information ( e.g. passive-interface ten 2/3).
• For a VLAN, enter the keyword vlan followed by a number
from 1 to 4094 (e.g. passive-interface vlan 2222).
E-Series ExaScale platforms support 4094 VLANs
with FTOS version 8.2.1.0 and later. Earlier ExaScale
supports 2094 VLANS.
