ipv6 ospf mtu-ignore
To disable IPv6 Open Shortest Path First (OSPF) maximum transmission unit
(MTU) mismatch detection on receiving database descriptor (DBD) packets, use
the ipv6 ospf mtu-ignore command in interface configuration mode. To reset to
default, use the no form of this command.
ipv6 ospf mtu-ignore [instance-id
INSTANCE-ID
]
no ipv6 ospf mtu-ignore [instance-id
INSTANCE-ID
]
Default
IPv6 OSPF MTU mismatch detection is enabled.
Command Mode
Interface configuration mode
Usage Guideline
IPv6 OSPF checks whether neighbors are using the same MTU on a common
interface. This check is performed when neighbors exchange DBD packets. If the
receiving MTU in the DBD packet is higher than the IP MTU configured on the
incoming interface, IPv6 OSPF adjacency will not be established.
Example
The following example disables MTU mismatch detection on receiving DBD
packets..
