Hello,
I can't find feature list of IOS XR 4.2.1 for ASR9K and can't find it in release notes of IOS XR 4.2.1.
Does IOS XR 4.2.1 support VRF Selection Using Source IP Address or VRF Selection Using ABF?
If it is not possible, what is the solution instead?
Thank you.

here you can find release notes for 4.2.1
VRF aware ABF is supported on ASR9k since 4.2.0.

I found it earlier, but I don't understand how to configure IOS-XR router
like this on IOS router:
access-list 40 permit source 10.1.0.0 0.0.255.255
access-list 50 permit source 10.2.0.0 0.0.255.255
access-list 60 permit source 10.3.0.0 0.0.255.255
!
route-map PBR-VRF-Selection permit 10
match ip address 40
set vrf VRF1
!
route-map PBR-VRF-Selection permit 20
match ip address 50
set vrf VRF2
!
route-map PBR-VRF-Selection permit 30
match ip address 60
set vrf VRF3
!
interface Ethernet 0/1
ip address 192.168.1.6 255.255.255.252 ip vrf forwarding VRF4
ip policy route-map PBR-VRF-Selection
ip vrf receive VRF1
ip vrf receive VRF2
ip vrf receive VRF3

Here is a configuration example:
!
ipv4 access-list ipv4-abf
10 permit ipv4 any any nexthop1 vrf 1 ipv4 10.10.1.2 nexthop2 vrf 2 ipv4 20.20.1.2 nexthop3 ipv4 30.30.1.2
!
ipv6 access-list ipv6-abf
10 permit ipv6 any any nexthop1 vrf 1 ipv6 2100::2 nexthop2 vrf 2 ipv6 2200::2 nexthop3 ipv6 2300::2
!
interface TenGigE0/1/0/12
ipv4 address 25.25.25.1 255.255.255.0
ipv6 address 2040::1/64
ipv4 access-group ipv4-abf ingress
ipv6 access-group ipv6-abf ingress
!

in fact I need this feature on IOS-XR
http://www.cisco.com/en/US/docs/ios/mpls/configuration/guide/mp_mltvrf_slct_pbr.html

There is no PBR on XR. You'd need to use ABF for NH manipulation which is in another VRF.
!
interface TenGigE0/1/0/12
ipv4 address 25.25.25.1 255.255.255.0
vrf VRF777
ipv4 access-group ipv4-abf ingress
!
!
ipv4 access-list ipv4-abf
40 permit ipv4 10.1.0.0 0.0.255.255 any nexthop1 vrf VRF1
50 permit ipv4 10.2.0.0 0.0.255.255 any nexthop1 vrf VRF2
60 permit ipv4 10.3.0.0 0.0.255.255 any nexthop1 vrf VRF3

Hi,
I am testing ABF on XR running on an old 12K in our lab, before upgrading few CRS in production.
Unforunately, cant seem to see ABF with NH as an option. I am running 4.2.3 in test.
Has thsi feature been scrapped off again ?
RP/0/3/CPU0:LAB-PE2(config-ipv4-acl)#permit ipv4 any any ?
dscp Match packets with given DSCP value
fragments Check non-initial fragments
log Log matches against this entry
log-input Log matches against this entry, including input interface
packet-length Check packet length
precedence Match packets with given precedence
RP/0/3/CPU0:LAB-PE2(config-ipv4-acl)#permit ipv4 any any
TIA

Hi Samir,
AFAIK, ABF isn't supported on XR12K but only on ASR9000 and CRS platforms.
Kind regards,
