GRE JUNOS

GRE Tunnel på juniper

For at lave en IPv4+IPv6 GRE tunnel imellem en Cisco IOS og en Juniper SRX skal der noget configuration til.

Junos

selve tunellen

[edit interfaces gr-0/0/0]
root@Router# show
unit 0 {
    description mercantec.elmholt.eu;
    tunnel {
        source yderside.domain1.com;
        destination yderside.domain2.com;
    }
    family inet {
        address 10.255.0.13/30;
    }
    family inet6 {
        address fec0::/64 {
            eui-64;
        }
    }
}

Og lidt configuration til en statick route

[edit routing-options]
root@Router# show
rib inet6.0 {
    static {
        route 2001:16d8:cafe::/48 next-hop fec0::cafe:cfff:fe96:f76e;
    }
}

Og hvis vi skal pinge skal der GRE interfacet være i trust zonen. Det er jo en SRX

[edit security zones security-zone trust]
root@Router# show
interfaces {
    gr-0/0/0.0;
}

På Cisco kassen

GRE interfaces

interface Tunnel0
 ip address 10.255.0.14 255.255.255.252
 ipv6 address FEC0::/64 eui-64
 tunnel source FastEthernet0/0
 tunnel destination yderside.domain1.com
end

og den staticke route

ipv6 route 2001:16D8:caff::/48 FEC0::cafe:cafe:DD:7500
