Hi,
Is there a way to automatically map routes to different TE tunnels based on some criteria like BGP communities for example?
I know we can map them based on CoS using CBTS, but can we do it based on communities?
In Juniper this can be done using "install-nexthop". Any similar way in Cisco?

Yes absolutely.
SR-TE AS/ODN does exactly this. You can instantiate TE policies based on BGP ext-community color attribute.
Please consult RFC5512 for further details:

Kind regards.

Hello,
I'm not aware of such feature in MPLS TE.
Consider though that PCEP, PCE, BGP-LS are not mandatory to run AS/ODN unless you're working on multi-area/level or interdomain path.
Regards
