Hi all,
the documentation says that for EIGRP to filter sap processing use a
distribute-sap-list under the eigrp process:
Control the Processing of SAP Updates
To control the processing of routes listed in incoming updates, perform the
following task in router configuration mode:
Task
Command
Control which incoming SAP updates are processed.
distribute-sap-list
access-list-number in [interface-name]
For a configuration example of controlling the processing of SAP updates,
see the "Advertisement and Processing of SAP Update Examples" section at
the end of
this chapter.
And the example is:
In the following example, the router redistributes Enhanced IGRP into NLSP
area1. Only services for networks 2 and 3 are accepted by the NLSP routing
process.
access-list 1000 permit 2
access-list 1000 permit 3
access-list 1000 deny -1
!
ipx router nlsp area1
redistribute eigrp
distribute-sap-list 1000 in
I have two static saps and want to filter only 1:
r3#show ipx servers
Codes: S - Static, P - Periodic, E - EIGRP, N - NLSP, H - Holddown, + = detail
U - Per-user static
2 Total IPX Servers
Table ordering is based on routing and server info
Type Name Net Address Port Route Hops Itf
E 4 server1 666.0000.0001.6666:0451
267033600/01 2 Se0
E 7 printer 666.0000.0002.6666:0451 267033600/01 2 Se
First I filtered using an input-sap-filter under the interface and made up
3 filters that all worked to filter one of these saps:
r3#show access-list
IPX sap access list 1000
permit FFFFFFFF 0 printer
deny FFFFFFFF
IPX sap access list 1001
permit 666 7
deny FFFFFFFF 0
IPX sap access list 1002
permit 666 4
deny FFFFFFFF 0
then I said - let's filter in EIGRP - but no luck. Both SAPS keep showing
up regardless of what I put in the access-list.
Question - when filtering SAPS in EIGRP distribute-sap-list - does it only
filter all saps from an entire network or can you filter
individual SAPs? If it is the entire network - then all of my lists will
permit network 666 and hence I get both saps.
