How to test

Config valid on 1.3

vyos@upgrade-test:~$ show config commands | grep local
set policy local-route rule 11 inbound-interface 'eth2'
set policy local-route rule 11 set table '11'
set policy local-route rule 11 source '203.0.113.0/24'
set policy local-route6 rule 66 fwmark '1001'
set policy local-route6 rule 66 inbound-interface 'eth3'
set policy local-route6 rule 66 set table '66'
set policy local-route6 rule 66 source '2001:db8::66'
vyos@upgrade-test:~$ 
vyos@upgrade-test:~$ sudo ip rule
0:	from all lookup local
11:	from 203.0.113.0/24 iif eth2 lookup 11
32766:	from all lookup main
32767:	from all lookup default
vyos@upgrade-test:~$ sudo ip -6 rule
0:	from all lookup local
66:	from 2001:db8::66 fwmark 0x3e9 iif eth3 lookup 66
32766:	from all lookup main
vyos@upgrade-test:~$

set policy ip-rule6 rule 66 inbound-interface 'eth3'
set policy ip-rule6 rule 66 set table '66'
set policy ip-rule6 rule 66 source address '2001:db8::66'
set system conntrack modules sip
vyos@upgrade-test:~$ sudo ip rule
0:	from all lookup local
11:	from 203.0.113.0/24 iif eth2 lookup 11
32766:	from all lookup main

I agree that this may reduce the confusion. But if we are opening the can of worms and writing a migration script anyway, maybe we should rethink all PBR syntax and see what else we can change?

We may want to change the approach to unify the "local-route" and "route" under a single subtree.

[nicolas-fort]

Marking as draft as we need to discuss this internally, in order to analyze if more changes should be included regarding PBR and ip-rules
