def _get_ipv4_source_router_id(self):
return self.__ipv4_source_router_id<EOL>
Getter method for ipv4_source_router_id, mapped from YANG variable /network_instances/network_instance/protocols/protocol/isis/levels/level/link_state_database/lsp/tlvs/tlv/extended_ipv4_reachability/prefixes/prefix/subTLVs/subTLVs/ipv4_source_router_id/state/ipv4_source_router_id (inet:ipv4-address-no-zone)

    YANG Description: IPv4 Source router ID address. In cases where the advertisement
is an identifier for the advertising router (e.g., with the
N-flag set in the Prefix Attribute Flags sub-TLV), it may be
useful for other routers to know the source of the
advertisement. When reachability advertisement is leaked from
one level to another, Router ID advertised is always the Router
ID of the IS-IS instance that originated the advertisement.
This would be true even if the prefix had been learned from
another protocol.
