CRS IOS XR 4.2.3 ABF IP SLA

budilasmono · ‎02-20-2013

Dear all,

I got a problem when running Access-List Based Forwarding (ABF / PBR) with IP SLA.

The Cisco document its says Object Tracking IP SLA with ABF is supported on IOS XR 4.2.1, even with the sample.

http://www.cisco.com/en/US/docs/routers/asr9000/software/asr9k_r4.1/addr_serv/configuration/guide/ipaddr_cg41a9k_chapter1.html#concept_4CBDF391A97345A084853EE73C280FCE

If i looked at Feature Navigator, IP SLA is already supported on IOS XR 4.1.1, with MPLS package software.

But when i configured on CRS, IP SLA cannot be attached on ABF.

Theres no option track on CLI, even if i specified track, CLI said error / invalid input.

Is there anything to make the ABF IP SLA run on CRS ?

Thanks,

Hi

You can try using following syntax

ipv4 access-list t1

10 permit ipv4 any any nexthop1 track t1 ipv4 1.1.1.1

Thanks

Hi All,

please help, how to configure ABF IP SLA on CRS-1 IOS XR ?

Thanks,
