Requirements
This lab shows how to configure a multiarea OSPF network and router ID.
Configuration
1. Basic & interface address configuration.
set system host-name JNCIE
set system root-authentication encrypted-password "$1$Luohd5lf$6ikSsNi1iEX/147eHbqm7."
set logical-systems R1 interfaces em1 unit 12 vlan-id 12
set logical-systems R1 interfaces em1 unit 12 family inet address 8.8.12.1/24
set logical-systems R1 interfaces lo0 unit 1 family inet address 1.1.1.1/32
set logical-systems R2 interfaces em2 unit 12 vlan-id 12
set logical-systems R2 interfaces em2 unit 12 family inet address 8.8.12.2/24
set logical-systems R2 interfaces em2 unit 23 vlan-id 23
set logical-systems R2 interfaces em2 unit 23 family inet address 8.8.23.2/24
set logical-systems R2 interfaces lo0 unit 2 family inet address 2.2.2.2/32
set logical-systems R3 interfaces em3 unit 23 vlan-id 23
set logical-systems R3 interfaces em3 unit 23 family inet address 8.8.23.3/24
set logical-systems R3 interfaces lo0 unit 3 family inet address 3.3.3.3/32
set interfaces em1 vlan-tagging
set interfaces em2 vlan-tagging
set interfaces em3 vlan-tagging
2. In logical-systems R1, I configure an OSPF router identifier and setup interface em1.12 & lo0.1(Passive) for OSPF area 0.
set logical-systems R1 routing-options router-id 1.1.1.1
set logical-systems R1 protocols ospf area 0.0.0.0 interface em1.12
set logical-systems R1 protocols ospf area 0.0.0.0 interface lo0.1 passive
3. In logical-systems R2, I configure an OSPF router identifier and setup interface em2.12 & lo0.2(Passive) for OSPF area 0.
Interface em2.23 for OSPF area 23
set logical-systems R2 routing-options router-id 2.2.2.2
set logical-systems R2 protocols ospf area 0.0.0.0 interface em2.12
set logical-systems R2 protocols ospf area 0.0.0.0 interface lo0.2 passive
4. In logical-systems R3, I configure an OSPF router identifier and setup interface em3.23 & lo0.3(Passive) for OSPF area 23.
set logical-systems R3 routing-options router-id 3.3.3.3
set logical-systems R3 protocols ospf area 0.0.0.23 interface em3.23
set logical-systems R3 protocols ospf area 0.0.0.23 interface lo0.3 passive
5. Commit the configuration.
