Hi,
I've a question about the command:
ip msdp filer-sa-request
http://www.cisco.com/en/US/docs/ios/ipmulti/command/reference/imc_03.html#wp1055553
ip msdp [vrf vrf-name] filter-sa-request {peer-address | peer-name} [list
access-list]
In the command reference description the access list should contain a multicast
group address:
list access-list
(Optional) Specifies the standard IP access list number or name that describes
a multicast group address. If no access list is specified, all SA request
messages are ignored.
In the example from the same command reference the access list contains a
unicast address.
ip msdp filter-sa-request 172.16.2.2 list 1
access-list 1 permit 192.4.22.0 0.0.0.255
The filter should permit SA requests from a MSDP peer only for groups matching
the access-list.
Is it an error in the command reference? Even in the configuration guide
description the ACL should containt multicast group(s):
http://www.cisco.com/en/US/docs/ios/ipmulti/configuration/guide/imc_msdp_im_pim_sm_ps6441_TSD_Products_Configuration_Guide_Chapter.html#wp1055820
You can filter a subset of SA request messages from a specified peer based on
groups defined in a standard access list by configuring the ip msdp
filter-sa-request command with the optional list keyword and access-list
argument. Issuing the form of the command effectively configures the router to
honor only SA request messages from the MSDP peer that match the groups defined
in a standard access list. SA request messages from the specified peer for
other groups will be ignored.
