MPLS 6PE

2023 Feb 21

MPLS 6PE MPLS 6PE is an IPv6 transition method that enables IPv6-only sites to be connected across an IPv4-only MPLS network. With this technology Service Providers can use existing IPv4 MPLS networks to connect IPv6-only sites. With MPLS 6PE dual stack IPv4/IPv6 PE routers are configured ...

MPLS 6VPE

2023 Feb 17

IPv6 L3VPN with MPLS 6VPE MPLS 6VPE enables connecting IPv6-only sites using an IPv4 MPLS network. This makes MPLS 6VPE an IPv6 transition method that leverages existing infrastructure to tunnel IPv6 traffic with label switching. As a result, Service Providers can use their IPv4 MPLS core networks to provide IPv6 services ...

IPv6 6to4 Tunnel Configuration

2023 Feb 16

IPv6 6to4 Tunnel Configuration 6to4 tunneling is a transition mechanism from IPv4 to IPv6 that enables IPv6-only sites to communicate with each other over an IPv4-only network. The prefix 2002:: /16 is used for 6to4 tunnels. IPv4 addresses are mapped to IPv6 and assigned to the tunnel interface. A 6to4 tunnel has an IPv4 source address ...

DMVPN with IPv6

2023 Feb 15

DMVPN with IPv6 DMVPN IPv6 can be configured across an IPv4-only transport network to provide connectivity between IPv6 locations. DMVPN IPv6 uses multipoint GRE tunnels to encapsulate IPv6 packets. Thus, a GRE header encapsulates IPv6 packets. In turn, an IPv4 header is used to encapsulate the GRE packet ...

EVPN IRB with Segment Routing

2023 Feb 14

EVPN IRB with Segment Routing A combination of relatively recent technology standards can be deployed to provision MPLS-based Layer-3 IP VPN services. Namely, Segment Routing can be configured as a transport service together with EVPN IRB to deploy Service Provider Layer-2 and Layer-3 VPNs using a unified BGP control plane ...

EIGRP OTP

2023 Feb 10

EIGRP OTP EIGRP OTP enables the creation of an overlay network between Customer Edge (CE) routers by using the LISP encapsulation. As a WAN technology connecting customer sites across one or more Service Providers (SP), EIGRP OTP offers a flexible mechanism to maintain control over IP routing ...

MPLS VPN with Backup FlexVPN

2023 Feb 9

MPLS VPN with Backup FlexVPN Running mission-critical applications in an enterprise headquarters and connecting large office buildings to a corporate WAN justify a redundant, high-availability infrastructure. With an MPLS Layer-3 VPN there are a variety of redundancy options ...

Carrier Supporting Carrier MPLS

2023 Feb 8

Carrier Supporting Carrier MPLS Carrier Supporting Carrier is a hierarchical MPLS VPN architecture where a Backbone Carrier provides transit services to a Customer Carrier. In such a design an MPLS VPN service is provisioned by the Backbone Carrier to be used by the Customer Carrier for its own MPLS VPN ...
