In this live chat with our tech expert, Mani, we'll discuss about the architecture, features, performance and benefits of Cisco ASR 1000 Series Routers. You'll also be able to ask your questions directly to the expert.
Please RSVP to join us live for the event. This event is open to all and will take place on our Facebook page.
About ASR1K Routers:
ASR1k is the Next-generation of Midrange router family 2.5 / 5 / 10 / 20+ Gbps forwarding with services Simple scale: 10-20-(40G) just by changing ESP
[5G-10G in 2RU and 2.5G in 2RU-fixed] Dual AC or DC power supplies
Designed for High Availability. Hardware redundancy for 6RU (RP and ESP) with ISSU. Software redundancy for 1RU/2RU/4RU: In-service software upgrade, even with one RP State of the art QoS (3 level, 128K+ queues) Integrated services, software-licensed based features (SBC, FW, NBAR, etc.) Powerful control plane in RP -Route Reflector apps
SPA support - same interfaces as 7600/12K/CRS-1 IOS features, CLI - simple migration from existing 7200 deployments

Re: Facebook Forum: Intro to Cisco ASR 1000 Series Aggregation R
Here's a condensed summary of the event.
I am looking for a base router for Core Routing running only OSPF. I would like to be able to handle 200 Mbps and about 1000 users. It should scale to 400 Mbps and about 5000 users. No firewall or VPN. What parts would I need for this ASR1000?
The forwarding ASIC, ESP, determines the scaling factor. ESP20 should fit the bill. If you are looking for hardware redundancy as well, ASR1006, ASR1013 should do with ESP20.
May I use ASR 1000 like vpls routers? Can you please talk about licensing policy for this service?
The ASR1k team is planning to support VPLS in IOS-XE 3.6S (March 2012). ASR1k products are honor based, except ASR1001, which needs license activation - think of it like Cisco's ISRG2 routers running universalk9 images.
What license/software would I need to support OSPF as a minimum and eBGP in addition?
It's better to to stay on any IOS-XE train from 15.0(1)S. The old ones, up to 12.2(33)XNF releases are end of software engineering. You don't need any license as long as you choose anything other than ASR1001.
When I disable fast switching on interface configuring "no ip route-cahe", ip cef is also disabled for that interface. Is this a normal behavior for ASR1K?
Fast switching is quite old now. For ASR1k they don't exist and CEF can't be disabled on ASR1k. If you attempt, you would see a message informing the same.
How many rsvp tunnels can asr with RP2 support at the same time?
It’s a brief answer, but I put this way: ASR1000/RP MPLS TE Headend: 1k MPLS TE Midpoints: 15k MPLS TE Tailends: 1k (ideally)
What are the major components of Cisco ASR 1000 Series?
The major components are: The Route processor RP, forwarding processor ESP and SIP - which houses SPA's.
What does “port status: secure down” mean? How do I change it so it says secure up?
Why is lsmpi_io always very low? Should I be suspecting a leak?
LSMPI (Linux Shared Memory Punt Interface) memory pool is being used to transfer packets/messages from the forwarding processor to the route processor. This memory pool is carved at router initialization into pre-allocated buffers, as opposed to the Processor pool where IOSXE can allocate memory blocks dynamically. It is therefore expected to see this low amount of free memory in lsmpi_io. In fact, it would be more of a concern to see a large amount of free memory for that pool as it would mean IOSXE wasn't able to allocate that memory. See this article for more information. https://supportforums.cisco.com/docs/DOC-16425
Is Arp a pak priority one with IOS-XE image on ASR1k?
It’s not enabled by default but, you can enable it with: Router(config-if)#arp packet-priority enable
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
