belonging to the template inherit the feature.
Example
OS10(config)# router bgp 10
OS10(conf-router-bgp-10)# neighbor
OS10(conf-router-bgp-10)# neighbor 1.1.15.4
OS10(conf-router-neighbor)# update-source Loopback 1

OS10(config)#router bgp 100
OS10(config-router-bgp-100)#
OS10(config-router-bgp-100)#vrf vrf_test1
OS10(config-router-bgp-100-vrf)#

Equal cost multi-path
ECMP is a routing technique where next-hop packet forwarding to a single destination occurs over multiple best paths. When
you enable ECMP, OS10 uses a hash algorithm to determine the next-hop. The hash algorithm makes hashing decisions based on
values in various packet fields and internal values.
