Each network domain typically runs an IGP which has complete visibility within its own domain, but limited visibility outside of its domain. Seamless Segment Routing (Seamless SR) provides flexible, scalable and reliable end-to-end connectivity for services across independent network domains. Seamless SR accommodates domains using SR, LDP, and RSVP for MPLS label distribution as well as domains running IP without MPLS (IP-Fabric).It also provides seamless connectivity across domains having different IPv6 technologies such as SRv6 and SRm6.}, }
