Prøv at konfigurer følgende setup på en Juniper SRX: BGP Demo Setup
Contents
Opgave
Grundlæggende forbindelser
- Konfigurer IP Adresser på alle Logical Tunnel interfaces
- De skal ligge i 10.255.0.X/30 netværkene
- LT interfacet skal have samme unit nummer som .4 oktet i op adressen(10.255.0.2 = lt-0/0/0.2)
- Configurer lo så de passer med <routernummer>x10. og en management adresse(PE1 = Lo0.10:10.255.255.1/32)
Konfiguration
Konfigurer de logiske interfaces og forbind dem
root@SRX240> <input>show configuration interfaces lt-0/0/0.2</input>
<notice>encapsulation ethernet;

family inet {

}

}
root@SRX240> <input>show configuration interfaces lo0.10</input>
family inet {
address 10.255.255.1/32;
}Opret en virtual router instance og forbind lt interfaces til instancen.

Kontroller at routerne har sat alle interfaces og IP adresser

3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max/stddev = 1.012/1.071/1.132/0.049 msBGP opsætning
- Lav en export regl til bgp
- Konfigurer lo0 interfacets ip adresse som router-id
- konfigurer eBGP imellem alle routerne.
Konfiguration
Lav en export regl i global routing instance
root@SRX240> <input>show configuration policy-options policy-statement VR-EBGP-EXPORT</input>
term 1 {
from {
protocol direct;
}
then accept;
}Konfigurer router-id og ASN under den virtuelle router.
[edit routing-instances]
