Hello XR Gurus,
We are currently doing some tests with internet full routing inside two VRFs and we are encountering some issues that we would like you to help.
Scenario:
IOS-XR with 4.2.3 P image
Trident LCs
RSP-4G
Only Two VRFs configured on the box, both with full routing
Issue:
We are sending 450K V4 prefixes, plus 25K V6 prefixes with 65K /24 prefixes per each /8, which should be inside the subtree limits. Still we are getting the following error message:
LC/0/0/CPU0:Feb 19 16:42:55.833 : prm_server_tr[295]: %PLATFORM-NP-3-OOR : Routing Table Full : PRM failed to install a route (114.255.239.0/24) because the subtree was full. Each subtree is limited to 262144 routes per subtree.Subtree where install failed is 114.0.0.0/8
Although, we get this error message we can see the prefix installed on CEF HW:
RP/0/RSP0/CPU0:A9K-LAB02#

Can anyone help us???
Thanks!!!

Hi,
Let us know what smu running on your router. Following output might be useful
show platform
show install active summary
Also check you have all the SMU recommended @

Hi Parthiv,
Yes we have pretty much all the recommended SMUs installed. Requested outputs are below:

Could you try following config.
vrf <> mode big
Please provide following
show cef ipv4 summary location all
show cef ipv6 summary location all
show tech cef
Thanks

Hi Parthiv,
Strangely (or not) it worked with "mode big"... However I do not understand why, since I only have two VRFs configured on the router. Any idea?
Do you still want the requested outputs?
Cheers,
Pedro

Hi Parthiv,
we did some more tests with and without "mode big". Please take a look at the bellow output:
