JUNOS 101 #2

#2 OSPF
1. Establish OSPF neighbors between EX-8216 over 10G link (area 0)
2. Configure Vlan1 in ospf area 1.

switch #1

protocols {
ospf {
area 0.0.0.0 {
interface xe-0/0/0.0;
}
}
}

interfaces {
xe-0/0/0 {
unit 0 {

}
}
}
}

switch #2

JUNOS 101 #1

I got a few Juniper boxes to test, 2 x EX-8216 and a few pizza boxes. This is the first time I am working on Junos boxes. These are configuration notes from my first days with Junos on EX-8216.

#1 BGP
Following configuration is
1. Establish a BGP session between two EX-8216
2. Redistribute static route into BGP
