Mumbai IX Technical Specifications & Descriptions

Allowed Traffic

Allowed Traffic Types on Unicast Peering LANs

Mumbai IX impose a set of restrictions on what kind of traffic is allowed on the peering fabric for ensuring smooth operation of its infrastructure. You can refer summary of those restrictions.

Port Security

The greatest danger to any Ethernet network consists of loops. Unless countermeasures are taken, a loop will instantly bring down any network. Broadcasts are looped back to the network, creating duplicates and loading the CPUs of all connected equipment, or in the worst case creating self-sustaining broadcast storms as broadcasts are fed back on another port and sent out on the first port again.

Quarantine VLAN

Mumbai IX has implemented a feature called “Quarantine VLAN” whereby all new ports are placed in their own separate VLAN, together with a monitor port.

Link Aggregation

To fill the gap between our 1 and 10 Gbit/sec port offerings, Mumbai IX also offers aggregated Gigabit Ethernet (GE) ports. To fill the gap between 10 Gbit/sec and 100 Gbit/sec Ethernet standard, Mumbai IX also offers aggregated 10GE ports.

Route-servers

Normally, customer need to maintain separate BGP sessions to each of your peers' routers. Customer can replace all or a subset of these sessions with one session towards each route server. The goal of the route server project is to facilitate the implementation of peering arrangements, and to lower the barrier of entry for new participants on the peering platform.

Important: The Mumbai IX NOC reserves the right to disable ports that violate the rules below.

Mumbai IX impose a set of restrictions on what kind of traffic is allowed on the peering fabric for ensuring smooth operation of its infrastructure. You can refer under of those restrictions.

Physical Connection

1. Interface settings

100base and 10base Ethernet interfaces attached to Mumbai IX ports must be explicitly configured with speed, duplex other configuration settings, i.e. they should not be auto-sensing.

2. MAC Layer
2.1 Ethernet framing

The Mumbai IX infrastructure is based on the Ethernet standard. This means that LLC/SNAP encapsulation (802.2) is not permitted.

2.2 Ethernet types

Frames forwarded to Mumbai IX ports must have one of the following ether types:

  • o0x0800 - IPv4
  • 0x0806 - ARP
  • o0x86dd - IPv6
2.3 One MAC address per port

Frames forwarded to an individual Mumbai IX port shall all have the same source MAC address. We also do MAC address binding with port.

2.4 No proxy ARP

Use of proxy ARP on the router's interface to the Exchange is not allowed.

2.5 Unicast only

Frames forwarded to MUMBAI IX ports shall not be addressed to a multicast or broadcast MAC destination address except as follows:

  • Broadcast ARP packets
  • Multicast ICMPv6 Neighbour Discovery packets. Please note that this does not include Router Solicitation or Advertisement packets
2.6 No link-local traffic

Traffic for link-local protocols shall not be forwarded to Mumbai IX ports.

Link-local protocols include, but are not limited to, the following list:

  • IRDP
  • ICMP redirects
  • IEEE 802 Spanning Tree
  • Vendor proprietary protocols. These include, but are not limited to:
  • Discovery protocols: CDP, EDP
  • VLAN/trunking protocols: VTP, DTP
  • Interior routing protocol broadcasts (e.g. OSPF, ISIS, IGRP, EIGRP)
  • BOOTP/DHCP
  • PIM-SM
  • PIM-DM
  • DVMRP
  • ICMPv6 ND-RA
  • UDLD
  • L2 Keepalives

The following link-local protocols are exceptions and are allowed:

  • ARP
  • IPv6 ND
3. IP Layer
3.1 No directed broadcast

IP packets addressed to MUMBAI IX peering LAN's directed broadcast address shall not be automatically forwarded to Mumbai IX ports.

4. IP addressing
4.1 no-export of Mumbai IX peering LAN

IP address space assigned to Mumbai IX Peering LANs shall not be advertised to other networks without explicit permission of Mumbai IX.

Mumbai IX Operations

Mumbai IX team is working 24X7X365 and it is reachable at techsupport@mumbaich.com or +91-70459551002

The problem from Mumbai IX team side can be escalated to senior management at its escalation email operations@mumbaich.com

Monitoring

Mumbai IX team is working 24X7X365 to monitor its infrastructure and its customers bgp status with Route server. Shift engineer inform customer if its link is down via email and provide support on phone too.

Mumbai IX has the mailing announce@mumbaich.com to inform its participants on performance degradation and service affecting events.
