in the ICMP unreachable messages and in the traceroute command output. The
loopback address must be unique in a particular domain.
In network environments that contain a large number of devices, ranging up to
thousands of systems, and with each device configured for equal-cost multipath
(ECMP) links, you cannot effectively and optimally use the traceroute and ping
applications to examine the network reachablity and identify any broken links for
diagnostic purposes. In such cases, if the reply that is obtained from each hop on the
network path contains the IP address of the adjacent, neighboring interface from which
the packet is received, it is difficult to employ the ping and traceroute utilites. You can
enable the ICMP unreachable messages to contain the loopback address of the source
device instead of the previous hop's IP address to be able to easily and quickly identify
the device and devices along the path because the DNS server maps the loopback IP
address to the hostname and does not translate the IP address of every interface of the
switch to the hostname
Example
Dell(conf)# ipv6 icmp source-interface tengigabitethernet 1/1/1
Dell(conf)#
ip max-frag-count
Set the maximum number of fragments allowed in one packet for packet re-assembly.
Syntax
ip max-frag-count count
To place no limit on the number of fragments allowed, use the no ip max-frag-
count command.
Parameters
count Enter a number for the number of fragments allowed for re-
assembly. The range is from 2 to 256.
Defaults No limit is set on number of fragments allowed.
