Introduction

The metalLB configMap file (mb_configmap.yaml) contains the manifest for the metalLB configMap, this defines the BGP peers and address pools for metalLB. This file (mb_configmap.yaml) must be placed in the same directory (/var/occne/<cluster_name>) as the hosts.ini file.

Table 2-2 Procedure to configure MetalLB pools and peers

Step #	Procedure	Description
1.	Add BGP peers and address groups	Referring to the data collected in the Preflight Checklist, add BGP peers (ToRswitchA_Platform_IP, ToRswitchB_Platform_IP) and address groups for each address pool. Address-pools list the IP addresses that metalLB is allowed to allocate.
2.	Edit the mb_configmap.yaml file	Edit the mb_configmap.yaml file with the site-specific values found in the Preflight Checklist Note: The name "signaling" is prone to different spellings (UK vs US), therefore pay special attention to how this signaling pool is referenced. configInline: peers: - peer-address: <ToRswitchA_Platform_IP> peer-asn: 64501 my-asn: 64512 - peer-address: <ToRswitchB_Platform_IP> peer-asn: 64501 my-asn: 64512 address-pools: - name: signaling protocol: bgp auto-assign: false addresses: - '<MetalLB_Signal_Subnet_IP_Range>' - name: oam protocol: bgp auto-assign: false addresses: - '<MetalLB_OAM_Subnet_IP_Range>'

Procedure

Description

Add BGP peers and address groups

Referring to the data collected in the Preflight Checklist, add BGP peers (ToRswitchA_Platform_IP, ToRswitchB_Platform_IP) and address groups for each address pool. Address-pools list the IP addresses that metalLB is allowed to allocate.

Edit the mb_configmap.yaml file

Edit the mb_configmap.yaml file with the site-specific values found in the Preflight Checklist

Note: The name "signaling" is prone to different spellings (UK vs US), therefore pay special attention to how this signaling pool is referenced.
