Adds scripts/generate_weathermap.py: fetches device inventory and
connectivity-matrix from IPFabric, cross-checks IPFabric's abbreviated
interface names against the live gnmic exporter, and emits a Grafana
dashboard-as-code JSON (configs/grafana/weathermap-dashboard.json) with
the weathermap-ng panel wired to explicit legendFormat-resolved queries
for BGP status, interface tx/rx, and VXLAN MAC-per-VNI.

Add prometheus node to the Containerlab topology, scraping the gnmic
exporter (172.16.0.70:9273) at 5s interval with relabeling to clean
device/interface/neighbor_address/vlan/mac_address/afi_safi labels.
Validated against BGP and system metrics confirmed in #44. Existing
external Prometheus instance stays untouched in parallel.
Refs #45
Add gnmic container node subscribing to interface, BGP, system, and
VXLAN gNMI paths across all Arista cEOS nodes, exposed via a
Prometheus exporter. gNMI runs in plaintext (no SSL profile on
management api gnmi), so insecure:true is used instead of TLS.

BusyBox ifup translates 'gateway X' into 'ip route add default via X'
and aborts the whole ifup run with RC=1 when that command fails with
'File exists' — which always happens on first boot because the docker
management bridge has already installed its own default via eth0. As a
result the 'post-up ip route replace default' was never executed and
the host kept the management default.
Remove the 'gateway' line so ifup only runs the idempotent 'post-up ip
route replace default via <fabric-gw>' and the fabric default wins.
Make hosts/campus-host{1,2}_interfaces the source of truth for the
campus host IP and default route, and have clab simply invoke 'ifup
eth1' at container start to apply it. Previously the bound interfaces
file was unused and the real config lived in the YAML exec block,
which was misleading.
BusyBox ifup in the network-multitool image needs 'address' plus
'netmask' rather than a CIDR, so split the address accordingly. Also
add 'post-up ip route replace default via <fabric-gw>' so the fabric
default overrides the management DHCP default even when one is already
installed.
The 'ip route add default via <fabric-gw>' exec command silently failed
on campus-host1 and campus-host2 because the management DHCP on eth0
had already installed a default via 172.16.0.254. As a result, traffic
leaving the host for other fabric subnets was sent out the management
interface instead of the EVPN fabric, breaking end-to-end ping.
Switch to 'ip route replace' so the fabric gateway overrides whatever
default is installed at container start.
With 'no bgp default ipv4-unicast' set at the router level, VRF gold
eBGP/iBGP neighbors were establishing but not exchanging any IPv4
prefixes, breaking inter-fabric transit between DC and Campus. Add an
explicit 'address-family ipv4' block with 'neighbor X activate' under
'vrf gold' on both cores and all four border leafs.
Also drop 'redistribute learned' from the border leaf VRF gold stanza:
it is not a valid command in that context and was silently stripped by
EOS.
- README: rewritten node inventory, AS map, addressing plan
(management, Lo0/Lo1, P2P, hosts), VNI/RD/RT tables, control-plane
summary and end-to-end Campus <-> DC test procedures through the
Core (VRF gold stitching).
- hosts/README: document the two new Campus host configurations.
- assets/arista-evpn-fabric.svg: new three-zone layout (Campus, Core,
DC) with legend.
- evpn-lab.clab.yml.annotations.json: reposition nodes and add zone
labels so the ContainerLab graph matches the extended topology.
core1/core2 provide L3 transit between DC and Campus fabrics. Each
physical link toward a Border Leaf is subinterfaced (.100 default,
.200 VRF gold). OSPF area 0 in default VRF, eBGP to DC BLs (65005)
and Campus BLs (66005), iBGP between core1 and core2 via Loopback0.
VRF gold uses redistribute connected and VRF-aware eBGP sessions on
.200 subinterfaces to stitch VRF gold end-to-end across fabrics.
Both border leafs share VTEP Loopback1 10.0.255.15 and peer with DC
spines in eBGP IPv4 + EVPN. Uplinks to core1/core2 use dot1q
subinterfaces (.100 default underlay, .200 VRF gold) with OSPF area 0
and eBGP to AS 65500. VRF gold extended via vxlan vrf gold vni 100001
with RD <Lo0>:1 and RT 1:100001.
The `evpn-lab.clab.yml.annotations.json` file was updated to remove all existing `freeTextAnnotations` (AS numbers) and `freeShapeAnnotations` (grouping rectangles). This effectively cleans up the visual overlay for the topology.
Update configuration files for all leaf and spine switches to include a
new static route for the 100.64.0.0/10 prefix.
The route points to the next-hop gateway 172.16.0.254, ensuring proper
reachability for the Tailnet range across the network fabric.
This commit updates the management interface configuration across all leaf and spine switches to align with the target environment requirements.
Changes include:
- Changing the primary management interface from `Management1` to `Management0`.
- Removing the `vrf mgmt` assignment, moving the interface to the default global routing table.
- Explicitly configuring `lldp management-address Management0` to ensure the correct management IP is advertised to neighbors.
Enables the gNMI (gRPC Network Management Interface) API across all leaf
and spine switches to allow for telemetry streaming and programmatic
device management.
Configuration details:
- Transport: grpc default
- Provider: eos-native
Add SVG topology diagram and containerlab annotations file with AS number labels and node positioning for the EVPN VXLAN lab environment.
