Hi, I’m trying to build a model for L3VPN provisioning with options. Options are: CE bgp routing and CE static routing.
Here’s a snippet of my yang model. You’ll see later on that variables like “intf-number” and “wan-ip-address” are being used properly, but variables within the “static” list are not. Or at least is not what I expected to happen and someone might offer me an explanation.
[snip]
leaf intf-number {
tailf:info "GigabitEthernet Interface ID";
mandatory true;
type string {
pattern "[0-9]{1,2}(/[0-9]{1,2}){1,4}";
}
}
leaf wan-ip-address {
tailf:info "IP Address of WAN Interface (X.X.X.X)";
mandatory true;
type inet:ipv4-address {
pattern "[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+";
}
}
[snip]
leaf routing-protocol {
tailf:info "PE<-->CE Routing Protocol";
mandatory true;
type enumeration {
enum bgp;
enum static;
}
}
list static {
tailf:info "Static Route for VRF";
key static-prefix;
when "../routing-protocol='static'";
leaf static-prefix {
tailf:info "Static Route Prefix";
mandatory true;
type inet:ipv4-address;
}
leaf static-mask {
tailf:info "Static Route Mask";
mandatory true;
type inet:ipv4-address;
}
[snip]
Here’s an extract of the XML template I’m using and that I expect the “static” list to fill out.
<ip xmlns="http://tail-f.com/ned/cisco-ios-xr">
<route tags='merge' when="{routing-protocol='static'}">
<vrf>
<name>{/vpn-name}</name>
<dest>{/static-prefix}</dest>
<dest-mask>{/static-mask}</dest-mask>
<forwarding-address>{/static-next-hop}</forwarding-address>
</vrf>
</route>
</ip>
Here’s what you see in the tail-f cli.

As you can see, the XR static ip route (see lines for static route configuration) is not filling out properly and the template uses only the variables that are outside of the static list node. Yet the services template at the very end sees the correct values in the variables (see xml services portion at the end). Everything else seems to work well and as expected.
Any advice would be appreciated.
Thanks,
c.
