Hi, I am using linux-cp and linux-nl plugins to install BGP routes in VPP and it is working fine for us. After this, we installed a sr policy and sr steering policy for an IPv4 prefix 81.81.81.0/64 and we want to advertise this prefix via BGP. Can we do it in a dynamic way using linux-cp and

Re: [vpp-dev] FIB entry being created on peer VPP node for the localsid

Hi Neale, Thank you. As mentioned in the post, we see a different behaviour on linux srv6 where it adds localsid as neighbor only and does not modify route table. So, why the handing for this is different in VPP? Thanks and Regards, Chinmaya Agarwal. -=-=-=-=-=-=-=-=-=-=-=- Links: You

Hi, We have a use case where we have two VPP nodes i.e. VN1 and VN2 , in a local redundancy testing setup, VN1 is acting as primary node and VN2 is acting as secondary node. VN1 has localsid configuration on it. VN2 has a neighbor and fib entry corresponding to the localsid of VN1. Now when we

[vpp-dev] API to use to fetch IP route information from VPP

Hi, We want to get ip route information from VPP using VAPI. We were referencing ip.api file, where we see two versions of ip route dump API i.e. ip_route_dump and ip_route_v2_dump. So, which one should we use for our implementation? Thanks and Regards, Chinmaya Agarwal.

[vpp-dev] Ping reply packets reaching vnet interface with correct vlan tags are not seen in VPP for VLAN interface.

Hi, We have two VMs running on Centos 8.4 and base server running on Centos 7.8. VM1 is running VPP(v21.06) and VM2 is a normal linux machine. VM1 is connected to VM2 on GigabitEthernet0/8/0 interface. We created a VLAN interface (with VLAN id 1400) on both the VMs and we are trying to ping
