Dynamic BGP Peering Primitive

The dynamic BGP peering primitive enables dynamic peering on selected devices and virtual networks.

The following parameters must be configured:

  • IPv4 AFI
  • IPv6 AFI
  • BGP Time to Live (TTL)
    • When you set TTL to 0, nothing is configured and the device defaults are used.
    • When you set TTL to 1, Cisco NX-OS and FRR-based BGP (SONiC) renders disable-connected-check. Otherwise, TTL values render ebgp-multihop on specific BGP neighbors.
  • Single-hop BFD
    • This enables BFD for the BGP peering. Multihop BFD is only supported for Junos, which is activated by default.
  • BGP Password
  • BGP Keep Alive Timer (seconds)
  • BGP Hold Time Timer (seconds)
  • IPv4
  • IPv6
  • IPv4 subnet for BGP prefix dynamic neighbors. If you leave this field blank, Apstra uses the local virtual network (from when you assigned the connectivity template) as the subnet value. In this case, if the virtual network only has a virtual gateway IP address, and it doesn't have any specific IP address per leaf switch, then it also renders an additional IP address on the leaf SVI besides the virtual gateway IP address.
  • IPv6 subnet for BGP prefix dynamic neighbors. If you leave this field blank, Apstra derives the subnet from the application point.
