Configuration Verification
When the source sends IP packets with correct IP options, the traffic is forwarded
properly.
When the source sends IP packets with incorrect IP options, the packets are dropped.

15.3 Configuring ICMP Unreachable Packet Function

Overview
If the router receives a non-multicast packet sent by an unknown protocol, the router
returns an ICMP unreachable packet to the source address. Similarly, if the router receives
a packet that cannot be sent to the destination (because the route to the destination is
unknown), it sends an ICMP host unreachable packet to the source address. By default,
ICMP unreachable packets are valid.
Configuration Commands
To configure the ICMP unreachable packet function, run the following commands on the
ZXR10 ZSR V2:
Command
ZXR10(config)#
ZXR10(config-icmp)#
ZXR10(config-icmp-if-interface-name)#
unreachable
Maintenance Commands

packet function is configured, run the following command. For other commands, refer to
