Cisco Meraki Security – Meraki MX Security Appliances
Meraki Cloud Managed Security Appliance Series
Today I am going to talk about Cisco acquired Meraki or Cisco Meraki MX Security Appliances. These appliances are ideal for organizations with large numbers of distributed sites. Since the MX is 100% cloud managed, installation and remote management is simple. So it means that these security appliances will be managed on cloud.The Meraki MX has a comprehensive suite of network services, eliminating the need for multiple appliances. These services include Layer 7 application firewall, content filtering, web search filtering with intrusion prevention, web caching, Intelligent WAN with multiple uplinks and 4G failover.

Security Features
- With the help of Meraki MX Security appliances we can have Application-aware traffic control which can set bandwidth policies based on Layer 7 application type (e.g., YouTube, Skype, P2P).
- Another best feature is the content Filtering which can be used as CIPA-compliant content filtering and safe search enforcement.
- Meraki based Intrusion prevention ( IPS feature) : PCI-compliant IPS sensor using industry-leading SNORT signature database from Cisco Sourcefire.
- With the help of Meraki MX security appliances, you can have the Anti-virus and anti-phishing with flow Continue reading

Episode 14 – Digging Deep into the IS-IS Routing Protocol
In a return to our routing protocol series, Russ White and Nick Russo join Network Collective to talk about some of the intricacies of the IS-IS routing protocol. While not usually found in enterprises, Service Providers have used IS-IS as the underlay to their MPLS networks and it is starting to make an appearance as the underlay to several newer enterprise technologies. If you’ve been curious about how it works, and how it is different than what you use today, this show is for you.

Show Notes
- IS-IS Characteristics
- IS-IS is a graph
- Vertices, edges, link types, cost
- Uses Dijkstra’s algorithm
- Based on Type Link Value protocol (TLV) instead of fixed type fields which allows IS-IS to be very extensible
- Similar to OSPF, but the P-node is called the DIS, not the DR, and behaves a bit differently
- Originally built for host routing
- Not an IP protocol
- direct encapsulation to L2, ethertype 0xFEFE
- Provides some inherent security benefits (very hard to reach in and attack; OSPF solved this with TTL security)
- QoS over L2VPNs
- If the EFP is matching IP DSCP for QoS, ISIS may not Continue reading

IPv6 prefix assignment BCOP published as RIPE-690
We’re pleased to announce that after a year of intensive work by IPv6 experts around the world, supported by the Deploy360 team, the RIPE community has reached consensus on the Best Current Operational Practices (BCOP) for IPv6 prefix assignment for end-users – persistent vs non persistent and what size to choose. These were officially published as RIPE-690 this week.
RIPE-690 outlines best current operational practices for the assignment of IPv6 prefixes (i.e. a block of IPv6 addresses) for end-users, as making wrong choices when designing an IPv6 network will eventually have negative implications for deployment and require further effort such as renumbering when the network is already in operation. In particular, assigning IPv6 prefixes longer than /56 to residential customers is strong discouraged, with /48 recommended for business customers. This will allow plenty of space for future expansion and sub-netting without the need for renumbering, whilst persistent prefixes (i.e. static) should be highly preferred for simplicity, stability and cost reasons.
The target audience of RIPE-690 is technical staff working in ISPs and other network operators who currently provide or intend to provide IPv6 services to residential or business end-users. Up until now, there have been no clear Continue reading
