Re: [vpp-dev] Problem in forwarding multicast traffic

Hi Juan, When setting multicast routes one must specify the accepting (or RPF) interface for the prefix. So, additionally, you need; ip mroute add 224.0.0.5 via GigabitEthernet0/7/0 Accept note though that while an interface can be configured to be both and accepting and forwarding interface

Hi nagp, We should remove the conditional CLIB_DEBUG from the declaration of FIB_PROTOCOL_IP4 in fib_types.h . It was there to assist me during development. But related errors have now been found and coverity checks enum type mismatches, so it’s save to be removed. I’ll push a patch shortly.

Re: [vpp-dev] admin_up_down flag for loopback interface

Hi Matej, Then you should remove the address from the interface – that in turn will remove the route from the FIB – and is in the only way that that route can be removed from the FIB. Regards, neale On 02/01/2017, 15:29, "Matej Klotton -X (mklotton - PANTHEON TECHNOLOGIES at Cisco)" wrote:

Re: [vpp-dev] Get IPv6 neighbors MACs

Hi Dmitry, IIUC you have two devices with identical IPv6 addresses, which we’ll call P and Q, connected on two different interfaces. These interfaces are in different VRFs so the addresses do not collide. Now if we succeed in importing the discovered neighbours from VRF 0 to VRF 1, these addr

Hi Calvin, The VPP MPLS code is not specific to any given interface type and so we support MPLS over all interface types that VPP supports. The logical separation is achieved because all MPLS LSPs (and IP routes too) are programmed in terms of next-hops, and any interface can be a next-hop. For

Re: [vpp-dev] How are dpo nodes plugged in the graph?

Hi Nagp, It picks up those next-nodes because it is a sibling of ip4-lookup – by definition siblings share next-nodes. The VLIB code ensures this by tracking sibling relationships and adding a next node to all siblings. Regards, neale From: on behalf of Nagaprabhanjan Bellaru Date: Wednesda
