IP performance optimization tasks at a glance

All IP performance optimization tasks are optional.

1. Configuring features for IP packets

   • Enabling an interface to forward directed broadcasts destined for the directly connected network

   • Setting the MTU of IPv4 packets sent over an interface

   • Enabling IPv4 local fragment reassembly

   • This feature is applicable in IRF networks.

2. Configuring features for ICMP messages

   • Enabling sending ICMP error messages

   • Configuring rate limit for ICMP error messages

   • Disabling forwarding ICMP fragments

   • Specifying the source address for ICMP packets

3. Configuring features for TCP packets

   • Setting TCP MSS for an interface

   • Configuring TCP path MTU discovery

   • Enabling SYN Cookie

   • Setting the TCP buffer size

   • Setting TCP timers
