Raw Blame History

Deployment & Testing Checklist

✅ What Was Fixed

  • Host VLAN tagging configuration in topology file
  • All 4 hosts now create VLAN subinterfaces (bond0.XX)
  • Leaf port-channels properly configured for access mode
  • BGP configuration in leafs includes ip routing command
  • MLAG configurations validated on all 4 leaf pairs
  • VXLAN VTEP configuration in place
  • EVPN overlay configuration complete

🚀 Deployment Steps

1. Check Current Branch

cd ~/arista-evpn-vxlan-clab
git branch
git status

Should show: fix-bgp-and-mlag branch

2. Destroy Current Lab (if running)

sudo containerlab destroy -t evpn-lab.clab.yml --cleanup

3. Deploy Fixed Lab

sudo containerlab deploy -t evpn-lab.clab.yml
# Wait 60-90 seconds for all containers to start

4. Verify Lab is Running

sudo containerlab inspect -t evpn-lab.clab.yml

Should show all 10 nodes (2 spines + 8 leaves + 4 hosts) as RUNNING

🔧 If Tests Fail

L2 ping fails

# 1. Check host VLAN interface
docker exec clab-arista-evpn-fabric-host1 ip addr show bond0.40

# 2. Check port-channel status
ssh admin@clab-arista-evpn-fabric-leaf1 "show interface Port-Channel1"
# Should show: up, up

# 3. Check VLAN 40 exists on leaf
ssh admin@clab-arista-evpn-fabric-leaf1 "show vlan 40"
# Should show: VLAN 40 exists

# 4. Check MAC learning (generate traffic)
docker exec clab-arista-evpn-fabric-host1 arping -c 3 10.40.40.1
ssh admin@clab-arista-evpn-fabric-leaf1 "show mac address-table vlan 40"
# Should show host1 MAC

L3 ping fails

# 1. Check VRF VLAN interface
ssh admin@clab-arista-evpn-fabric-leaf3 "show interface Vlan34"
# Should show: up, up

# 2. Check VRF routing enabled
ssh admin@clab-arista-evpn-fabric-leaf3 "show ip route vrf gold"
# Should show routes

# 3. Check VXLAN VRF mapping
ssh admin@clab-arista-evpn-fabric-leaf3 "show interface Vxlan1"
# Should show: vxlan vrf gold vni 100001

📝 Notes for Next Steps

  1. If all tests pass ✅

    • Create pull request to merge fix-bgp-and-mlag into main
    • Document the changes in FIXES_APPLIED.md
    • Update main branch documentation

  2. If specific tests fail ⚠️

    • Review the troubleshooting section above
    • Check device logs: show log
    • Review configuration with show running-config

  3. Keep for reference

    • END_TO_END_TESTING.md - Comprehensive testing guide
    • VLAN_TAGGING_FIX_EXPLANATION.md - Explains the root cause and fix
