A Dell EMC Networking S4048 configuration details
A.1 Configuration of S4048-10 for Layer 3 IP-Cloud
1. Enter the following commands to configure the Layer 3 interfaces between the spine/core and leaf
switches:
mk-S4048-10# conf t
mk-S4048-10(config)# interface ethernet1/1/2
mk-s4048-10(conf-if-eth1/1/2)# des link_2_S4048-11
mk-s4048-10(conf-if-eth1/1/2)# no switchport
mk-s4048-10(conf-if-eth1/1/2)# ip add 155.13.1.1/24
mk-s4048-10(conf-if-eth1/1/2)# exit
mk-s4048-10(config)# int range eth1/1/4-1/1/5
mk-s4048-10(conf-range-eth1/1/4-1/1/5)# des link_2_S4048-8
mk-s4048-10(conf-range-eth1/1/4-1/1/5)# no switchport
mk-s4048-10(conf-range-eth1/1/4-1/1/5)# exit
mk-s4048-10(config)# interface eth1/1/4
mk-s4048-10(conf-if-eth1/1/4)# ip add 155.14.1.1/24
mk-s4048-10(conf-if-eth1/1/4)# exit
mk-s4048-10(config)# interface eth1/1/5
mk-s4048-10(conf-if-eth1/1/5)# ip add 155.15.1.1/24
mk-s4048-10(conf-if-eth1/1/5)# end
mk-s4048-10#
2. Configure the local loopback to use as the update source interface:
mk-s4048-10# conf
mk-s4048-10(config)# interface loopback0
mk-s4048-10(conf-if-lo-0)# ip add 1.1.1.1/24
mk-s4048-10(conf-if-lo-0)# end
mk-s4048-10#
3. Configure the BGP and related eVPN configurations.
Note: There are different autonomous areas (AS) that are defined. The spine and leaf switches are
configured in different AS numbers.
mk-s4048-10# conf
mk-s4048-10(config)# router bgp 10
mk-s4048-10(conf-router-bgp-10)# address-family ipv4 unicast
mk-s4048-10(conf-router-bgpv4-af)# redistribute connected
mk-s4048-10(conf-router-bgpv4-af)# exit
mk-s4048-10(config-router-bgp-10)# neighbor 155.13.1.3 <<< link to Leaf 1
mk-s4048-10(config-router-neighbor)# remote-as 20
mk-s4048-10(config-router-neighbor)# address-family ipv4 unicast
mk-s4048-10(config-router-bgp-neighbor-af)# no sender-side-loop-detection
mk-s4048-10(config-router-bgp-neighbor-af)# exit
mk-s4048-10(config-router-neighbor)# exit
mk-s4048-10(config-router-bgp-10)# neighbor 3.3.3.3 <<<< Leaf 2 loopback
