The Cisco SLASR1-IPB-AIS is a Product Activation Key (PAK) upgrade license that transitions Cisco ASR 1000 series routers from the IP Base software feature set to Advanced IP Services. This upgrade delivers enhanced capabilities for service providers and enterprises, including full encryption support (IPsec, 3DES, AES, SSH), lawful intercept, Session Border Control (SBC), Cisco IOS Flexible Packet Matching (FPM), Network-Based Application Recognition (NBAR), Zone-Based Policy Firewall, and broadband aggregation.
Cisco ASR 1000 Series Overview
Cisco ASR 1000 series aggregation services routers redefine edge routing with Cisco QuantumFlow processors, offering performance from 2.5 Gbps to 100 Gbps. Models include fixed-configuration ASR 1001, ASR 1002 Fixed, ASR 1002, ASR 1002-X, modular ASR 1004, ASR 1006, and ASR 1013 chassis. Key innovations include separated control and data planes for software/hardware redundancy, In-Service Software Upgrade (ISSU), and embedded services without additional blades.
Key Benefits of IP Base to Advanced IP Services Upgrade
- Provides service provider-grade features: encryption for secure VPN aggregation (up to 8000 IPsec tunnels, 25 Gbps crypto performance on ESP100), deep packet inspection, firewall (2.5-100 Gbps), and QoS with 232,000 queues.
- Supports enterprise WAN edge, hosted CPE, broadband L2TP LAC/LNS (up to 64,000 sessions/users), L3VPN provider edge (4M IPv4/IPv6 routes, 8K VRFs), high-end route reflector (29M IPv4 routes), and Unified Border Element SP edition (up to 32K sessions, 40 Gbps media).
- Enables modular QoS CLI (MQC) for hierarchical policies, priority queuing, bandwidth limiting based on DSCP, NBAR, FPM classification.
- Simplifies management with embedded services in QuantumFlow processor, reducing OpEx/CapEx through consolidation.
Software Architecture and Redundancy
Cisco IOS XE modular OS supports dual IOS instances on single RP for software redundancy (ASR1001, ASR1002-F/X, ASR1004) or hardware redundancy (ASR1006/1013). Feature sets: IP Base (basic IP), Advanced IP Services (full crypto, no legacy protocols), Advanced Enterprise Services (legacy protocols). Upgrade via SLASR1-IPB-AIS activates AIS on universal images like SASR1001UK9/SASR1002XUK9.
Performance and Scalability
QuantumFlow processors deliver 10x performance over prior midrange routers. ESP options scale throughput: ASR1001 (2.5-5Gbps), ASR1002-X (5-36Gbps), up to 100Gbps on larger chassis. Embedded hardware encryption: up to 25Gbps on ESP100. Supports IPv4/IPv6, multicast, BGP, OSPF, IS-IS.
Enterprise Applications
- WAN edge QoS for application availability: VLAN/channel MQC policies, 232K queues, priority propagation.
- IPsec VPN aggregation: 8000 tunnels, scales to 100Gbps chassis.
- Embedded Zone-Based Firewall: 2.5-100Gbps, 40K sessions/sec NetFlow v9 logging.
- Hosted CPE: SLA routing, WAN optimization, firewall/NAT (1.8-25Gbps crypto).
Service Provider Applications
- Broadband LAC/LNS: 64K users/sessions, per-user firewall/SBC.
- L3VPN PE: 29M routes, 64K adjacencies, 400M IPv4/IPv6 routes, 4K ACLs.
- Route Reflector: 29M IPv4 routes, 8-16GB DRAM options.
- Unified Border Element (SP): 32K calls, IPv4/IPv6 unicast/multicast, accounting, QoS, firewall.
Hardware Integration
Chassis feature integrated RP/ESP/SIP (1-2RU fixed, 4-13RU modular), Gigabit Ethernet ports (4-6 built-in), IDC options (T3, OC3, GE, T1/E1, HDD). Supports extensive SPAs: serial/channelized, Ethernet (FE/GE/10GE), PoS, ATM, SyncE, services (WebEx, DSP, CEoP).
Management and Reliability
IOS XE subpackages (RPBase, RPControl, RPAccess, RPIOS, ESPBase, SIPSPA, SIPBase) allow granular upgrades. Dual IOS for SSO/ISSU. High availability with low-downtime design.
