How to filter VPN4 address using route-map

2025-02-22 Thread Ramanathan Selvamani
Hi Team, I would like to filter a VPN4 address using route-map. For example, I have the below VPN4 address learnt through BGP neighbor on "L2VPN EVPN" channel. Table vpntab4: 1:222 90.0.0.0/24unicast [EVPN_4_4_4_4 2025-02-21] * (160) 1:100 60.0.0.0/24unicast [BGP_4_4_4_4 17:45:37.617 from

Route-type 5 support in BGP EVPN

2024-10-27 Thread Ramanathan Selvamani
Hi Team, I would like to know about the below two things in BIRD support (1) Do you have any plan to support BGP EVPN Route-Type 5 (IP Prefix Route) as defined in RFC 9136 in the BIRD EVPN branch. (2) Do you have any plan to support two level recursive lookup to resolve nexthop for BGP routes. I

Hi Team, I am resending the line of code again since the last mail was not showing up correctly. memcpy(mls.stac*k*, &a->nh.label[a->nh.labels - mls.len], mls.len * sizeof(u32)); Thanks. On Fri, 12 Apr 2024 at 09:58, Ramanathan Selvamani wrote: > Hi Team, > >

Hi Team, I have tried to use mpls_label_stack to keep some meta data for each route. But the values of meta data were not copied correctly. I just found the below code in "rt_next_hop_update_rte" function in rt-table.c memcpy(*mls.**stack*, &a->nh.label[a->nh.labels - mls.len], mls.len * sizeof

Different export route target for different prefixes of a same VRF

Hi Team, I configured l3vpn in BIRD and I was able to see the routes are learnt and advertised based on RT. All the routes in this VRF are advertised with RT (1:11) to neighbors. I have a use case in which I want to apply different RT for different routes belonging to the same VRF. For example,

Thanks for your response. I assume that with L3VPN support it is possible to set up one interface for many VRFs. May I know how to do it? Could you please share any sample BGP configuration for L3VPN ? Thanks, Ramanathan On Wed, 29 Mar 2023 at 13:41, ch wrote: > On 29/03/2023 09.28, Ramanat

Hi Team, I am using linux kernel 4.14 and trying to bind 2 vrfs to the same BGP instance. The BGP session is established. But the second VRF binding over-writes the first VRF binding. Do bird support this 2 vrf binding to the same BGP instance ? R1 == ipv4 table T_VRF_RED; ipv4 table T_VRF_
