| Security | - Cisco IOS XR Software: Provides ACLs, control-plane protection, routing authentication, AAA and TACACS+, SSH, SNMPv3, and advanced RPL support. - Layer 2 ACLs: Filters packets under an EVC based on MAC addresses. - Layer 3 ACLs: Matches IPv4 packets based on Layer 3 attributes. - Additional security features: 802.1ad L2CP and BPDU filtering; MAC limiting per EFP or bridge domain; unicast, multicast, and broadcast storm-control on any interface or port; Unknown Unicast Flood Blocking (UUFB); DHCP snooping; URPF; control-plane security; Dynamic ARP Inspection (DAI); and IP Source Guard (IPSG). |
| Multicast | - IPv4 Multicast: Supports IGMPv2/v3, PIM-SSM, PIM-SM, PIM SSM Mapping, MSDP, Multicast VPN, and Anycast RP. - IGMP v2 and v3 snooping: Layer 2 snooping on VLAN or pseudowire level, summarizing joins upstream so only watched channels are sent downstream, ideal for broadband video deployments. |
| MPLS L3VPN | - MPLS L3VPN: Scalable IPv4 Layer 3 VPN backbone services for IP VPNs, supporting value-added services such as applications, data hosting, e-commerce, and telephony for business customers. - Carrier supporting carrier (CSC): Allows an MPLS VPN provider to use another backbone while maintaining private address space for customer VPNs, per IETF RFC 4364. - Selective VRF Download: Downloads VRF FIB entries only to line cards with VRF membership to increase chassis FIB scale and avoid unnecessary entries. - 6PE and 6VPE: Introduce IPv6 from the edge over an IPv4/MPLS backbone without IPv6 addressing restrictions, minimizing risk and operational cost. |
