ASR9006 - unable to allocate label

Marcin Kurek

Level 1

Hello,

I'm running some tests on our new ASR9006s and I ran into a problem when feeding full BGP table into a VRF.

We are using the following RSP and LCs:

A9K-RSP440-TR

A9K-MOD80-TR

A9K-MOD160-TR

I've set the VRF mode as 'big', but once the router receive 530k IPv4 prefixes the BGP session is torn down and I get an error message:

RP/0/RSP0/CPU0:May 15 03:37:00.947 : bgp[1046]: %ROUTING-BGP-3-ERR_ALM_ONE_LABEL : [7] : Unable to allocate label: 'MPLS_LSD' detected the 'resource not available' condition 'Code(0)': No space left on device - net 192.76.32.0/22 tableid 0xe0000012 request type 3 fpi_err:0x0

I didn't change label allocation scheme, so it's per-prefix, but this should not be a problem, because this platform is capable of 1M locally generated labels, is that correct?

What might be the issue here?

Marcin,

 

the hardware you have does support 1M, the default label range is 256K, to increase to 1M use the following command:

mpls label range 16000 1048575
