Hi,
I checked the module ietf-i2rs-rib.yang with pyang and it generates a
pretty long list of errors. The problem seems to be in all cases that
the module defines the same data nodes in multiple cases of a choice.
For example, grouping "tunnel-encap" contains this (schematically):
choice tunnel-type {
case ipv4 {
uses ipv4-header;
}
case nvgre {
choice nvgre-type {
case ipv4 {
uses ipv4-header;
}
...
}
}
...
}
So the same data nodes defined by the "ipv4-header" grouping appear in
both "ipv4" and "nvgre/ipv4" cases, which is not possible in YANG.
One remedy could be to encapsulate the individual cases in specific
containers.
