Does Batfish support parsing Cisco's IS-IS IPv6 Multi Process configuration?

[LXZ230901]

Does Batfish support parsing Cisco's IS-IS IPv6 Multi Process configuration? example config:

vrf definition v1 rd 200:1 ! router isis v1a vrf v1 net 49.000b.0000.0001.0002.00 is-type level-1 log-adjacency-changes address-family ipv6 redistribute isis v1b route-map abc redistribute isis level-1 into level-2 distribute-list xyz

'net 49.000b.0000.0001.0002.00 is-type level-1 log-adjacency-changes' always reports an error during use;

Batfish does not support IPv6. However, we often add parsing at a minimum to make bf.q.undefinedReferences() or bf.q.unusedStructures() not produce invalid output.

What type of analyses are you looking to do here?

thanks,I want to configure one or more vrfs under the isis process,but I meet some issues during the parsing process,as shown in the following example:

import pandas as pd
from pybatfish.client.session import Session
from pybatfish.datamodel import *
from pybatfish.datamodel.answer import *
from pybatfish.datamodel.flow import *

TXT="""
!
hostname example_debug
!
vrf definition v1
 rd 200:1
!
router isis v1a 
 vrf v1
  net 49.000b.0000.0001.0002.00
  is-type level-1
  log-adjacency-changes
  address-family ipv6
   redistribute isis v1b route-map abc
   redistribute isis level-1 into level-2 distribute-list xyz
"""

bf = Session(host="localhost")

bf.set_network('example_bug')

bf.init_snapshot_from_text(TXT)

print(bf.q.initIssues().answer())

It seems batfish doesn't support configuring an isis process for a specific vrf.

@dhalperi In other words,does batfish support to parse multiple VRF-aware IS-IS instances?
