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.

The no encapsulation VXLAN layer-3 set next-hop igp-cost or default encapsulation VXLAN layer-3 set next-hop igp-cost command removes all the IGP cost for VTEP running configurations on the switch.

Command Mode

BGP Address-Family Configuration

Command Syntax

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

no encapsulation VXLAN layer-3 set next-hop igp-cost

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

Example

The following command configures the IGP cost for VTEP feature on the switch :

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

e-tree

VLAN Configuration Mode

Command Syntax

vlan vlan_id e-tree role leaf

Parameters

vlan vlan_id - Specify the VLAN to configure E-Tree.
e-tree - Specify configuring E-Tree.
role - Specify the role of the VLAN.

Examples

Use the following command to set VLAN 100 as an E-Tree leaf role:

switch(config)#vlan 100
            switch(config-vlan-100)#e-tree role leaf

To return the VLAN to the E-tree role root, use the following command:

switch(config)#vlan 100
            switch(config-vlan-100)#no e-tree role leaf

leak routes

Command Mode

Router General Configuration

Command Syntax

leak routes source-vrf source_name subscribe-policy route_map

no leak routes source-vrf source_name

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

Command Syntax

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.

vlan-aware-bundle corporate_100
  rd 1.1.1.1:100
  route-target both 100:100
  vlan 1-10

vlan-aware-bundle corporate_100
  rd 1.1.1.1:100
  route-target both 100:100
  vlan 1-10, 1000
  
switch(config-vlan-aware-bundle)#vlan remove 5

(Updated configuration for corporate_100)
vlan-aware-bundle corporate_100
  rd 1.1.1.1:100
  route-target both 100:100
  vlan 1-4, 6-10, 1000

vni-aware-bundle
