[j-nsp] Convert Cisco BGP configs to Juniper (M10i)

[Chen, Qinxue]

Thanks a lot.

It looks like the conversion lost several important things:

1) For Cisco side "update-source Loopback0", may I use "local-address x.x.x.x" on Juniper?
2) For Cisco side "send-community", is this a default behavior on Juniper?
3) For Cisco side "no synchronization", is this a default behavior on Juniper?
4) For the same peer-group, the outbound policies should be the same. Should we move the outbound policies out of the neighbor section and apply them at the group level? In the conversion, it looks like you can have different outbound policies for different neighbors in the same peer-group. 

Am I right?

Thanks

Qinxue

If you have access to Juniper's support site, use the I2J tool, which does
the conversion for you:

https://i2j.juniper.net/release/index.jsp

Here's the output from your config. It should be tweaked a little bit
though.

routing-options {
    autonomous-system 666;
}
protocols {
    bgp {
        log-updown;
        group Reflector {
            type external;
            peer-as 777;
            neighbor 1.2.3.4 {
                export [ bgp-redistributes bgp-policies-Reflector-1-export
];
                import bgp-policies-Reflector-1-import;
            }
        }
    }
}
policy-options {
    policy-statement bgp-policies-Reflector-1-export {
        term next-hop-self {
            then {
                next-hop self;
                next term;
            }
        }
        term explicit-default-action {
            then next policy;
        }
    }
    policy-statement bgp-policies-Reflector-1-import {
        term term-1 {
            from policy ( ! rm-MapY );
            then reject;
        }
        term explicit-default-action {
            then next policy;
        }
    }
    policy-statement bgp-redistributes {
        term direct {
            from {
                policy rm-MapX;
                protocol direct;
            }
            then accept;
        }
        term static {
            from {
                policy rm-MapX;
                protocol static;
            }
            then accept;
        }
        term from-bgp {
            from protocol bgp;
            then next policy;
        }
        term ios-implicit-deny {
            then reject;
        }
    }
    policy-statement rm-MapX {
        term ios-implicit-deny {
            then reject;
        }
    }
    policy-statement rm-MapY {
        term ios-implicit-deny {
            then reject;
        }
    }
}
