15.1 Configuring ICMP Fast Response
Overview
Opposite to the ICMP slow response function, the ICMP fast response function reduces
delays and delay jitter of ping packets, and increases the standard-reaching rate of network
delays.
To detect the connectivity with another node, one node uses the ICMP response function.
The source node sends an ICMP Echo Request packet to the destination node. After
receiving this packet, the destination node returns an ICMP Echo Reply packet. When
the source node receive the corresponding Reply packet, it determines that the network is
connected.
The ICMP slow response function means that a destination node sends received Request
packets to the control plane, which returns Reply packets. To reduce delays, the ICMP
fast response function directly returns Reply packets.
Configuration Commands
To configure the ICMP fast response function, run the following command on the ZXR10
