E-Tree Commands

Display Commands

bfd vtep evpn

The bfd vtep evpn command to configure the BGP PIC Edge for evpn VXLAN routes for remote VTEPs. This command is configured under the VXLAN Tunnel Interface (VTI).

The no bfd vtep evpn command removes bfd vtep evpn configuration from the running-config.

Command Mode

VXLAN Tunnel Interface (VTI) Mode

Command Syntax

bfd vtep evpn interval interval-milliseconds min-rx min-rx-milliseconds multiplier multiplier-range

no bfd vtep evpn interval interval-milliseconds min-rx min-rx-milliseconds multiplier multiplier-range

Parameters
  • interval Set transmit rate in milliseconds.
    • interval-milliseconds Rate in milliseconds. Value ranges from 50 to 60000 milliseconds.

  • min-rx Set expected minimum incoming rate in milliseconds.
    • min-rx-milliseconds Rate in milliseconds. Value ranges from 50 to 60000 milliseconds.

  • multiplier Sets the BFD multiplier.
    • multiplier-range The value ranges from 3 to 50.

Example

In this example (assuming symmetric configuration on other PE devices) any BFD for VXLAN session initiated on the VTI would have a detect time of 300ms (interval of 100ms multiplied by 3). 
switch(config-if-Vx1)# bfd vtep evpn interval 100 min-rx 100 multiplier 3

encapsulation VXLAN layer-3 set next-hop igp-cost

The encapsulation VXLAN layer-3 set next-hop igp-cost command configures the underlay IGP metric for the VTEP reachability to be considered for BGP best path selection in the IP VRF that is importing the evpn route.

Command Mode

BGP Address-Family Configuration

Command Syntax

switch(config-router-bgp)# address-family evpn
switch(config-router-bgp-af)# [no | default] encapsulation VXLAN layer-3 set next-hop igp-cost

Command Syntax

[vlan vlan_id] e-tree role leaf

Parameters

  • vlan vlan_id - Specify the VLAN to configure E-Tree.

vlan (VLAN-AWARE-Bundle configuration mode)

The vlan add/ remove command configures the VLAN range string in a VLAN-AWARE-BUNDLE. When the add and remove options are not used, the currently configured range is replaced by the new one. The add and remove options update the currently configured range-aware bundles by adding or removing the provided VLAN range from the currently configured range respectively.

Command Mode

VLAN-AWARE-BUNDLE Configuration

vlan [add | remove] range

Parameter

range  is the range specified.

Example

These commands take an existing vlan-aware-bundle configuration, corporate_100, and modify it with the add and remove options.
