This command configures Internet Control Message Protocol (ICMP) parameters on a VPRN service.

This command enables responses to ICMP mask requests on the router interface.
If a local node sends an ICMP mask request to the router interface, the mask-reply command configures the router interface to reply to the request.
By default, the router instance replies to mask requests.
The no form of this command disables replies to ICMP mask requests on the router interface.

This commad configures the rate for ICMP redirect messages issued on the router interface.
When routes are not optimal on this router and another router on the same subnetwork has a better route, the router can issue an ICMP redirect to alert the sending node that a better route is available.
The redirects command enables the generation of ICMP redirects on the router interface. The rate at which ICMP redirects are issued can be controlled with the optional number and seconds parameters by indicating the maximum number of redirect messages that can be issued on the interface for a specified time interval.
By default, the generation of ICMP redirect messages is enabled at a maximum rate of 100 per 10 second time interval.
The no form of this command disables the generation of icmp redirects on the router interface.
redirects 100 10
Specifies the maximum number of ICMP redirect messages to send. This parameter must be specified with the seconds parameter.
Specifies the time frame, in seconds, used to limit the number of ICMP redirect messages that can be issued.
ttl-expired number seconds
no ttl-expired

This command configures the rate ICMP TTL expired messages are issued by the IP interface.
By default, the generation of ICMP TTL expired messages is enabled at a maximum rate of 100 per 10 second time interval.
The no form of this command disables the limiting the rate of TTL expired messages on the router interface.
ttl-expired 100 10
Specifies the maximum number of ICMP TTL expired messages to send, expressed as a decimal integer. This parameter must be specified with the seconds parameter.
Specifies the time frame, in seconds, used to limit the number of ICMP TTL expired messages that can be issued, expressed as a decimal integer.
unreachables [number seconds]
no unreachables

Supported on all 7210 SAS platforms as described in this document
This command configures the rate for ICMP host and network destination unreachable messages issued on the router interface.
The rate at which ICMP unreachables is issued can be controlled with the optional number and seconds parameters by indicating the maximum number of destination unreachable messages that can be issued on the interface for a specified time interval.
By default, the generation of ICMP destination unreachable messages is enabled at a maximum rate of 100 per 10 second time interval.
The no form of this command disables the generation of ICMP destination unreachable messages on the router interface.
unreachables 100 10
Specifies the maximum number of ICMP unreachable messages to send. This parameter must be specified with the seconds parameter.
Specifies the time frame in seconds used to limit the number of ICMP unreachable messages that can be issued.
ip-mtu octets
no ip-mtu
config>service>vprn>if
Supported on all 7210 SAS platforms as described in this document
This command configures the maximum IP transmit unit (packet) for the interface.
The MTU that is advertised from the VPRN size is:
MINIMUM((SdpOperPathMtu - EtherHeaderSize), (Configured ip-mtu))
By default (for Ethernet network interface) if no ip-mtu is configured, the packet size is (1568 - 14) = 1554.
The no form of this command reverts to the default value.
no ip-mtu
Specifies the number of octets in the IP-MTU.
