The following features are configured for this POC:
- The interfaces used in this POC are 100 GbE except the interfaces to the servers, which are 10/25 GbE.
- LLDP is enabled by default.
- Layer 3:
- All Layer 3 interfaces and VLANs with IP addresses are configured with an MTU of 9100 bytes.
- The fabric is configured with BGP unnumbered.
- eBGP is configured in the fabric.
- ECMP is configured between the leaf and spine switches.
- ASN allocations are unique on the leaf and spine switches:
- Leaf 1 and Leaf 2—ASN# 65001
- BLeaf 25 and BLeaf 26—ASN# 65025
- Spine 1 and Spine 4—ASN# 65000
- VRF
- VRF in leaf, single tenant setup:
- Vrf-tenant1 (Tenant1) for overlay (EVPN) routes
- Default VRF for underlay routes and connectivity
- VRF in leaf, single tenant setup:
- Monitoring:
- Syslog—Interface logs, BGP session logs, and chassis-related (PSU, fan, temperature) syslog alerts
- SNMP—Enabled SNMPv2 queries and destination for SNMP traps
- IP prefixes
