Due to a ransomware attack, the wiki was reverted to a July 2022 version. . We apologize for the lack of a more recent valid backup.
- transit traffic (traffic from one BGP peer outside local SDN network traverses local SDN network and goes to another BGP peer) are proactively installed by SDN-IP application
- one host wants to talk to another host, both two hosts are in SDN network.
- one host in SDN network wants to talk to another host in Internet.
- one host from Internet wants to talk to another host in SDN network.
Even if you only want run reactive routing for local traffic, which means case 2 above. You still need to run SDN-IP APP.
one example of the configuration file is:
{
"ports" : {
"of:00000000000000a1/4" : {
"interfaces" : [
{
"ips" : [ "201.0.0.254/24" ],
"mac" : "00:00:00:00:00:01"
}
]
},
"of:00000000000000a2/3" : {
"interfaces" : [
{
"ips" : [ "202.0.0.254/24" ],
"mac" : "00:00:00:00:00:01"
}
]
},
"of:00000000000000a6/3" : {

}
]
},
"of:0000000000000a13/4" : {

{

},
{

"type" : "PUBLIC",

{

"gatewayIp" : "206.0.0.254"
},
{
"ipPrefix" : "213.0.0.0/24",

}
}
}
}
If you want to make all the scenarios work, including 1. 2. 3. 4. Then you should config both SDN-IP APP and ReactiveRouting APP. One config example is:
{
"ports" : {
"of:00000000000000a8/5" : {
"interfaces" : [
{
"ips" : [ "10.0.5.101/24" ],
"mac" : "00:00:00:00:00:01"
}
]
},
"of:0000000000000a32/4" : {
"interfaces" : [
{
"ips" : [ "10.0.4.101/24" ],
"mac" : "00:00:00:00:00:01"
}
]
},
"of:0000000000000a28/3" : {
"interfaces" : [
{
"ips" : [ "10.0.6.101/24" ],
"mac" : "00:00:00:00:00:01"
}
]
},
"of:00000000000000a1/4" : {
"interfaces" : [
{
"ips" : [ "201.0.0.200/24" ],
"mac" : "00:00:00:00:00:01"
}
]
},
"of:00000000000000a2/3" : {
"interfaces" : [
{
"ips" : [ "202.0.0.200/24" ],
"mac" : "00:00:00:00:00:01"
}
]
},
"of:00000000000000a6/3" : {
"interfaces" : [
{
"ips" : [ "206.0.0.200/24" ],
"mac" : "00:00:00:00:00:01"
}
]
},
"of:0000000000000a13/4" : {
"interfaces" : [
{
"ips" : [ "213.0.0.200/24" ],
"mac" : "00:00:00:00:00:01"
}
]
}
},
"apps" : {
"org.onosproject.router" : {
"bgp" : {
"bgpSpeakers" : [
{
"connectPoint" : "of:0000000000000a24/1",
"peers" : [
"10.0.4.1",
"10.0.5.1",
"10.0.6.1"
]
}
]
}
},
"org.onosproject.reactive.routing" : {
"reactiveRouting" : {
"ip4LocalPrefixes" : [
{
"ipPrefix" : "201.0.0.0/24",
"type" : "PUBLIC",
"gatewayIp" : "201.0.0.254"
},
{
"ipPrefix" : "202.0.0.0/24",
"type" : "PUBLIC",
"gatewayIp" : "202.0.0.254"
},
{
"ipPrefix" : "206.0.0.0/24",
"type" : "PRIVATE",
"gatewayIp" : "206.0.0.254"
},
{
"ipPrefix" : "213.0.0.0/24",
"type" : "PRIVATE",
"gatewayIp" : "213.0.0.254"
}
],
"ip6LocalPrefixes" : [
],
"virtualGatewayMacAddress" : "00:00:00:00:00:01"
}
}
}
}
Since "201.0.0.0/24" and "202.0.0.0/24" are public IP prefixes, you should also config them inside BGP speakers inside SDN network.
