IETF 122 Hackathon

Setup

1. Clone the repository with submodules:

   git clone --recurse-submodules https://github.com/watal/ietf122_hackathon
   cd ietf122_hackathon/gobgp/cmd/gobgp

2. Build GoBGP:

   go build .
   cd ../gobgpd
   go build .

3. Build the Docker image:

   cd ../../../bgp-ls-service-segment
   docker build . -t ubuntu:watal

4. Deploy the network using [containerlab]:

   sudo containerlab deploy -t bgp-ls-service-segment-gobgp-only.clab.yml

GoBGP (Sender Side)

1. Enter the GoBGP container:

   docker exec -it clab-bgp-ls-service-segment-gobgp-only-gobgp1 bash

2. Start the GoBGP daemon:

   gobgpd -f config/gobgpd.yml

3. Add a route:

   gobgp global rib add -a ls srv6sid bgp identifier 1 local-asn 65001 \
     local-bgp-ls-id 10 local-bgp-router-id 10.0.0.1 local-bgp-confederation-member 1 \
     sids fc00:0:1::2 multi-topology-id 1 service-type 1 traffic-type 1 \
     opaque-type 1 value test

GoBGP (Receiver Side)

1. Enter the GoBGP container:

   docker exec -it clab-bgp-ls-service-segment-gobgp-only-gobgp2 bash

2. Start the GoBGP daemon:

   gobgpd -f config/gobgpd.yml

3. Display the BGP-LS information:

   gobgp global rib -a ls

ExaBGP (Sender Side)

1. Enter the ExaBGP container:

   docker exec -it clab-bgp-ls-service-segment-exabgp bash

2. Start ExaBGP in sender mode:

   sbin/exabgp ../config/conf-srv6-bgpls-sender.conf

ExaBGP (Receiver Side)

1. Enter the ExaBGP container:

   docker exec -it clab-bgp-ls-service-segment-exabgp bash

2. Navigate to the ExaBGP directory:

   cd exabgp/

3. Start ExaBGP in receiver mode:

   sbin/exabgp ../config/conf-srv6-bgpls-receiver.conf

4. To stop ExaBGP, press Ctrl+C.

5. Check the logs to verify:

   cat bgpls-receiver.log
