How to find all routes that are going out an interface in IOS-XR.

[acivciss]

Hi all,

So if I have the following set up in IOS:

interface GigabitEthernet7/0/0.265

encapsulation dot1Q 265

ip vrf forwarding test

ip address 1.1.1.1 255.255.255.252

ip verify unicast reverse-path

end

ip route vrf Apollo 2.2.2.0 255.255.255.248 1.1.1.2

I can see all the routes that are going out the interface using show ip cef command:

ios-router#show ip cef vrf test GigabitEthernet7/0/0.265

2.2.2.0/29

  nexthop 1.1.1.2 GigabitEthernet7/0/0.265

1.1.1.0/30

  attached to GigabitEthernet7/0/0.265

1.1.1.2/32

  attached to GigabitEthernet7/0/0.265

In case of IOS-XR (ASR9K 4.3.2 or 4.3.1) the same setup and command shows only

attached routes:

router static

vrf test

  address-family ipv4 unicast

   2.2.2.0/29 1.1.1.2

RP/0/RSP0/CPU0:TST_riga-sb7-pe-asr9#show cef vrf test bundle-ether2.265

Prefix              Next Hop            Interface

1.1.1.0/30          attached            Bundle-Ether2.2220333

1.1.1.0/32          broadcast           Bundle-Ether2.2220333

1.1.1.1/32          receive             Bundle-Ether2.2220333

1.1.1.2/32          1.1.1.2             Bundle-Ether2.2220333

1.1.1.3/32          broadcast           Bundle-Ether2.2220333

Is there any command to see all the routes that are going out an interface without complicated parsing

of the configuration, recursive show cef commands etc.?

You can accomplish this with the "show route" command.  Here is an example:

P/0/RSP1/CPU0:ASR9006-E#sh route next-hop tenGigE 0/3/0/2

Tue Oct  8 15:34:58.046 UTC

Codes: C - connected, S - static, R - RIP, B - BGP

       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

       E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP

       i - ISIS, L1 - IS-IS level-1, L2 - IS-IS level-2

       ia - IS-IS inter area, su - IS-IS summary null, * - candidate default

       U - per-user static route, o - ODR, L - local, G  - DAGR

       A - access/subscriber, - FRR Backup path

Gateway of last resort is 172.18.87.1 to network 0.0.0.0

D    10.95.248.1/32 [90/128512] via 10.129.56.210, 4d00h, TenGigE0/3/0/2

C    10.129.56.208/30 is directly connected, 4d00h, TenGigE0/3/0/2

L    10.129.56.209/32 is directly connected, 4d00h, TenGigE0/3/0/2

O    10.242.142.240/30 [110/20] via 10.129.56.210, 3d11h, TenGigE0/3/0/2

                       [110/20] via 10.129.56.214, 3d11h, TenGigE0/3/0/3

D    192.168.1.16/32 [90/128512] via 10.129.56.210, 4d00h, TenGigE0/3/0/2

D    192.168.20.39/32 [90/128512] via 10.129.56.210, 4d00h, TenGigE0/3/0/2
