I'm not sure I understand...that's the problem I'm running into. Because I'm touching over 450 routers per script, and because there are multiple flavors of configuration changes, it is one big long script. If a router is unavailable, it hangs.

My thoughts were that before spawn telnet ran, a ping would make sure that the IP address replied, and if it did it could proceed. If it did not reply, then go to the next spawn telnet, etc.

I'm obviously a router Cisco guy first, not a programmer, so I do apologize if I'm making no sense.

mrinfo

mrinfo(8)						      System Manager's Manual							 mrinfo(8)

NAME

       mrinfo - Displays configuration information from a multicast router

SYNOPSIS

       /usr/sbin/mrinfo [-d debug_level] [-r retry_count] [-t timeout_count] multicast_router

OPTIONS

       Sets  the  debug  level. When the debug level is greater than 0 (the default), additional debugging messages are printed. Regardless of the
       debug level, if an error condition occurs, mrinfo writes an error message and terminates.  Nonzero debug levels have the following effects:
       Prints  packet  warnings to stderr.  Prints all level 1 messages and notifications of down networks to stderr.  Prints all level 2 messages
       and notifications of all packet timeouts to stderr.  Specifies the number of times to retry a neighbor query.  The default  is  3  retries.
       Specifies the number of seconds to wait for a neighbor to reply to a query. The default timeout is 4 seconds.

DESCRIPTION

       The mrinfo command displays the configuration information from the multicast router multicast_router.

       The  mrinfo command sends the ASK_NEIGHBORS IGMP message to the specified multicast router.  If the multicast router responds, the response
       includes the version number and a list of addresses for their neighboring multicast routers.  If the responding router has a recent  multi-
       cast  version  number, mrinfo requests additional information such as metrics, thresholds, and options from the multicast router.  Once the
       specified multicast router responds, the configuration is displayed to the standard output.

RESTRICTIONS

       You must be superuser in order to run mrinfo.

EXAMPLES

       The following example shows the output of the mrinfo command where  mbone.phony.dom.net	is  specified  as  the	multicast  router:  mrinfo
       mbone.phony.dom.net 127.148.176.10 (mbone.phony.dom.net) [version 3.3]:
	127.148.176.10 -> 0.0.0.0 (?) [1/1/querier]
	127.148.176.10 -> 127.0.8.4 (mbone2.phony.dom.net) [1/45/tunnel]
	127.148.176.10 -> 105.1.41.9 (momoney.com) [1/32/tunnel/down]
	127.148.176.10 -> 143.192.152.119 (mbone.dipu.edu) [1/32/tunnel]

       For  each  neighbor of the queried multicast router, the IP address of the queried router is displayed, followed by the IP address and name
       of the neighbor. In square brackets, the metric (cost of connection) and the threshold (multicast ttl) are displayed. If the queried multi-
       cast router has a newer version number, the type (tunnel, srcrt) and status (disabled, down) of the connection are displayed.
