Configures a candidate bootstrap router for PIM sparse-mode operation.
| ipv4 | Specifies the IPv4 address family. |
| ipv6 | Specifies the IPv6 address family. |
| vlan_name | Specifies a VLAN name. |
| priority | Specifies a priority setting. The range is 0 - 255. |
| none | Deletes a CBSR. |
The default setting for priority is 0, and indicates the lowest priority.
The VLAN specified for CBSR must have PIM enabled for it to take effect. After PIM is enabled, CBSRs advertise themselves in the PIM domain. A bootstrap router (BSR) is elected among all the candidates based on CBSR priority. To break the tie among routers with the same priority setting, the router with the numerically higher IP address is chosen.
An ExtremeXOS switch can support up to 145 RPs per group when it is configured as a PIM BSR (bootstrap router). If more than 145 RPs are configured for a single group, the BSR ignores the group and does not advertise the RPs. Non-BSR switches can process more than 145 RPs in the BSR message.
The following example configures a candidate bootstrap router on the VLAN accounting:
configure pim cbsr vlan accounting 30
