SNMP query not showing all XR ISIS neighbors

I don't seem to be able to get SNMP information on a second ISIS process running on an XR device with the following specs:

Hardware: ASR 9904

Software: Version 5.3.3

Here are the neighbors I know the router has and the SNMP MIB support:

RP/0/RSP1/CPU0:router1#sh isis neighbors
Wed Jun 28 16:43:25.918 BST
IS-IS PROCESS1 neighbors:
System Id Interface SNPA State Holdtime Type IETF-NSF
router2 Te0/0/1/0 *PtoP* Up 29 L2 Capable
router3 Te0/0/1/1 . *PtoP* Up 27 L2 Capable
Total neighbor count: 2

IS-IS PROCESS2 neighbors:
System Id Interface SNPA State Holdtime Type IETF-NSF
router4  BE1.1 *PtoP*. Up 28 L1 Capable
Total neighbor count: 1

RP/0/RSP1/CPU0:router1#

As you can see from the above output, there are 3 ISIS neighbors. Two in PROCESS1 and one in PROCESS2. 

However when I do an snmpwalk on the device, I only get information for the two ISIS neighbors in PROCESS1. 

stevenc@mymachine$ snmpwalk -v 2c -c s3cr3t router1 1.3.6.1.2.1.138.1.6.2
SNMPv2-SMI::mib-2.138.1.6.2.1.2.19.7.1 = Hex-STRING: 49 01 00 23 45
SNMPv2-SMI::mib-2.138.1.6.2.1.2.21.5.1 = Hex-STRING: 49 01 00 56 78
stevenc@mymachine$

I'm not sure why. It could be the fact that it is a separate process or it could be the fact that the third ISIS neighbor is off of a sub-interface. Or it could be something else entirely. 

Can anyone assist?

Both OSPF MIB and ISIS MIB only support 1 process

I think it might be helpful to add the this has been solved by specifying contexts for SNMP. 

I originally saw this post and dismissed it as a "it doesn't work and refer to these docs as proof."

 

But it really was a " Cisco has solved this issue with the following mechanisms."
