Dell EMC SmartFabric OS10 User Guide Release 10.5.1

You can create peer templates to add multiple neighbors at a time to the nondefault VRF instance that you create.

1. Enable BGP, and assign the AS number to the local BGP speaker in CONFIGURATION mode, from 1 to 65535 for 2 bytes, 1 to 4294967295 | 0.1 to 65535.65535 for 4 bytes, or 0.1 to 65535.65535, in dotted format.

   router bgp as-number

2. Enter CONFIG-ROUTER-VRF mode to create a peer template for the nondefault VRF instance that you create.

   vrf vrf-name

3. Create a peer template by assigning a neighborhood name to it in CONFIG-ROUTER-VRF mode.

   template template-name

4. Add a neighbor as a remote AS in ROUTER-TEMPLATE mode, from 1 to 65535 for 2 bytes, 1 to 4294967295 | 0.1 to 65535.65535 for 4 bytes, or 0.1 to 65535.65535, in dotted format.

   neighbor ip-address

5. Add a remote neighbor, and enter the AS number in ROUTER-TEMPLATE mode.

   remote-as as-number

   • To add an EBGP neighbor, configure the as-number parameter with a number different from the BGP as-number configured in the router bgp as-number command.
   • To add an IBGP neighbor, configure the as-number parameter with the same BGP as-number configured in the router bgp as-number command.
6. (Optional) Add a text description for the template in ROUTER-TEMPLATE mode.

   description text

7. Assign a peer-template with a peer-group name from which to inherit to the neighbor in ROUTER-NEIGHBOR mode.
   • For peers with an IP address:

     inherit template template-name

   • For peers with unnumbered interfaces:

     inherit template template-name inherit-type {ebgp | ibgp}

8. Enable the neighbor in ROUTER-BGP mode.

   neighbor ip-address

9. Enable the peer-group in ROUTER-NEIGHBOR mode.

   no shutdown

A neighbor may keep its configuration after it is added to a peer group if the neighbor configuration is more specific than the peer group and if the neighbor configuration does not affect outgoing updates.

To display the peer-group configuration that is assigned to a BGP neighbor, use the show ip bgp peer-group peer-group-name command. The show ip bgp neighbor command output does not display peer-group configurations.

Configure peer templates

OS10(config)# router bgp 300
OS10(config-router-bgp-300) vrf blue
OS10(config-router-vrf)# template ebgppg
OS10(config-router-template)# remote-as 100
OS10(config-router-template)# description peer_template_1_abcd
OS10(config-router-template)# exit
OS10(config-router-vrf)# neighbor 3.1.1.1
OS10(config-router-neighbor)# inherit template ebgppg
OS10(config-router-neighbor)# no shutdown
