An engineer is troubleshooting BGP on a device but discovers that the clock on the device does not correspond to the time stamp of the log entries. Which action ensures consistency between the two times?
In OSPF (Open Shortest Path First), the MTU (Maximum Transmission Unit) size must match on both sides of a link for OSPF neighbors to form an adjacency12.If the MTU sizes do not match, the OSPF adjacency will not form, and the routers will not become neighbors12.
In this case, R1 cannot establish a neighbor relationship with R2.One possible reason for this could be a mismatch in the MTU size on the interfaces of R1 and R212.
To resolve this issue, you can configure themtu ignorecommand on the interfaces of R1 and R2 (Option A).This command allows OSPF to ignore the MTU size when determining if it can form an adjacency with a neighbor12.This means that even if the MTU sizes do not match, OSPF will still form an adjacency, and R1 and R2 will become neighbors12.
