ip tcp adjust-mss

Use to enable the sending of redirect messages if the software is forced to resend a
packet through the same interface on which it was received.
Example
host1(config-if)#ip redirects
Use the no version to remove the assignment from the profile.
See ip redirects
Use to modify the maximum segment size (MSS) for TCP SYN packets traveling through
the interface. The router compares the MSS value of incoming or outgoing packets
against the MSS adjustment value. For any packet that contains an MSS value larger
than the MSS adjustment value, the router replaces the MSS option with the configured
adjustment value. If the packet does not contain an MSS value, the router assumes a
value of 536 for the packet MSS on which to base the comparison.
NOTE: The purpose behind using MSS is to alleviate problems with Path
MTU Discovery (PMTUD) and resulting "black hole" detection issues. (See
RFC 2923, "TCP Problems with Path MTU Discovery," for additional
information about the "black hole" scenario.)
Example
host1(config-if)#ip tcp adjust-mss 5000
Use the no version to remove the MSS assignment from the profile.
See ip tcp adjust-mss
Use to specify the numbered interface with which dynamic unnumbered interfaces
created with the profile are associated.
You can specify an unnumbered interface using RADIUS instead of using the ip
unnumbered command in a profile.
Example
host1(config-profile)#ip unnumbered fastEthernet 0/0
Use the no version to remove the assignment from the profile.
See ip unnumbered
Use to assign a virtual router to a profile.
You can configure a virtual router using RADIUS instead of adding one to the profile
by using the ip virtual-router command.
