Abstract
Methods and systems are described for providing route advertisements to provider edge devices on virtual private networks implemented using different protocols. An illustrative method includes receiving, from a first provider edge device on a first virtual private network (VPN), a route advertisement in a first format, wherein the first format corresponds to a first standard, determining whether the first format is translatable to a second format, wherein the second format corresponds to a second standard, in response to determining that the first format is translatable to the second format, identifying parameters for translating a route included in the route advertisement from the first format into the second format, generating a translated route advertisement by translating the route included in the route advertisement in accordance with the identified parameters, and transmitting, to a second provider edge device on a second VPN, the translated route advertisement including the translated route.
