[c-nsp] IOS XR OSPF redistribute to eBGP

[Ahmed Sharif]

Hi Aaron,

Let's focus on outbound only. Yes you are correct, I am not using RTs and I want it to be achieved using route-policy just like you mentioned below.
For out bound you defined the route-policy "ipv4-allow-out" in which you referenced "send-to-isp".
Can you show me the example configuration of "send-to-isp" ? Kindly note that the prefix I want to advertise is an ospf route.

route-policy ipv4-allow-out
  if destination in send-to-isp then
    pass
  else
    drop
  endif
  end-policy

Regards,
Ahmed

Since you are talking about vrf routes into bgp I guess you don't need RT's but I'm not entirely sure... I see you don't have RT's in your vrf.

I wonder if you need the network/23 in the vrf context under bgp... like...

router bgp 65201
vrf OM_InBand_TME_PE
 Network x.x.x.x/23

...here's my vrf context under my bgp for network's I advertise to my isp...

router bgp 64512
 vrf one
  rd 10.101.101.101:1
  address-family ipv4 unicast
   aggregate-address 1.2.3.0/20 summary-only
   aggregate-address 2.4.6.0/19 summary-only

  neighbor 3.1.3.1
   remote-as 6789
   local-as 1369 no-prepend replace-as
   address-family ipv4 unicast
    route-policy ipv4-allow-in in
    route-policy ipv4-allow-out out

...also, I'm not sure of the difference between "done" and "pass" in a route-policy... but I use "pass"

RP/0/RSP0/CPU0:eng-lab-9k-1(config-rpl)#if destination in testit then ?
....
  done              Accept this route with no further processing
....
  pass              Pass this route for further processing
...

...here's my outbound...

route-policy ipv4-allow-out
  if destination in send-to-isp then
    pass
  else
    drop
  endif
  end-policy
!

RP/0/RSP0/CPU0:grdn-9k#sh run prefix-set send-to-isp Fri Apr 22 18:30:47.346 CDT prefix-set send-to-isp
  1.2.3.0/19,
  2.4.6.0/20,
  end-set

I don't see your inbound route-policy.... so maybe that's a problem too for getting the 0/0 route from your isp...

Here's my inbound to allow 0/0 from my isp...

route-policy ipv4-allow-in
  pass
  end-policy
!
