Usage

Information

You can configure the amount of time for which the device must wait before it attempts to establish a

TCP connection. Using this capability, you can limit the wait times for TCP connection requests. Upon

responding to the initial SYN packet that requests a connection to the router for a specific service (such

as SSH or BGP) with a SYN ACK, the router waits for a period of time for the ACK packet to be sent

from the requesting host that will establish the TCP connection.

ip unknown-unicast

Enable IPv4 catch-all route.

S6000

Syntax

ip unknown-unicast [vrf vrf-name]

To remove the IPv4 catch-all route (0.0.0.0/0) from the LPM route forwarding table in hardware which

gets added as a default configuration after the initialization of FIB Agent module, use the no ip

unknown-unicast command.

Defaults None

Parameters
