IPv4 ABF nexthops routed over GRE interfaces are supported?

Supported for NCs-5501-SE?

Found this from ->

However, while inside GRE tunnel configuration (tunnel-ip) , there's no option for

ipv4 access-group

Hi,

the packet comes in on a physical interface, hits the ABF and is routed out a GRE tunnel.

this is what is supported on the NCS5500, not abf inside GRE tunnel interface

Thanks

my requirement is to "policy route" the traffic sourced from GRE tunnel to specific outgoing next hop. In this case, i suppose it is not supported ?

Hi,

pbr on gre, that may not work on this router.  you may have to do something "creative".

such as connect port 1 and port 2 together, have GRE traffic exit port 1, put ABF on port 2 to route to next hop.

something like this.

maybe someone else reading these posts may have a better idea.

Thanks

this router have too many limitations.
