Abstract
In one embodiment, a network device determines identities of each peer device in a second routing domain attached to edge devices in a first routing domain. The network device associates each address prefix reachable in the second routing domain with an identity of each peer device in the second routing domain that advertised the address prefix and with an identity of one or more edge devices in the first routing domain to which that peer device is attached. The network device determines an address prefix is associated with a same identity of a peer device in the second routing domain but with different edge devices in the first routing domain. The network device assigns the different edge devices in the first routing domain associated with the determined address prefix to a shared risk node group (SRNG).
