What is source-based routing Isilon?

Source-based routing selects which gateway to direct outgoing client traffic through based on the source IP address in each packet header. In another example, a client on SubnetC, which is not connected to the Isilon cluster, makes a request to SmartConnect ZoneA and ZoneB. …

When to use source-based routing?

Source-based routing, often referred to as policy routing, is used when the source IP address of the connection determines, in part or completely, which route is used. Source-based routing can be used to ensure that traffic is sent via a specific connection.

How do I configure source-based routing?

PBR on Cisco router can configure using following steps:

  1. Step1: Configure ACLs. Permit statement in ACL is what will be matched.
  2. Step2: Configure route map instances.
  3. Step3: Configure match commands.
  4. Step4: Configure set commands.
  5. Step5: Configure PBR on the interface.
  6. Step6: (Optional) Configure local PBR.

How do I find my DNS Isilon?

Procedure

  1. Click Cluster Management > Networking Configuration .
  2. In the DNS Settingsarea, click Edit.
  3. In the Domain name server(s) field, enter up to three domain name server IP addresses.
  4. In the DNS search list field, enter up to six DNS search suffixes.

What is strict source routing?

Strict Source Routing is an option whereby a source of a datagram provides routing information through which a gateway or host must send the datagram.

What is the source of IP source routing?

Source routing is a feature of the IP protocol which allows the sender of a packet to specify which route the packet should take on the way to its destination (and on the way back). Source routing was originally designed to be used when a host did not have proper default routes in its routing table.

Which is the IP source routing method?

Why do we need segment routing?

Segment routing (SR) is a source-based routing technique that simplifies traffic engineering and management across network domains. It removes network state information from transit routers and nodes in the network and places the path state information into packet headers at an ingress node.

Why is BGP policy based?

Policy-based routing is used for the following main reasons: To control traffic flow direction either by source or destination address. To change the next hop address. To change the way traffic is sent to a neighboring router.

How to enable source based routing in Isilon cluster?

In the following example, you enable source-based routing on an Isilon cluster that is connected to SubnetA and SubnetB. Each subnet is configured with a SmartConnect zone and a gateway, also labeled A and B. When a client on SubnetA makes a request to SmartConnect ZoneB, the response originates from ZoneB.

How does source based routing work in a cluster?

Source-based routing is applied across the entire cluster and only supports the IPv4 protocol. Enabling or disabling source-based routing goes into effect immediately. Packets in transit continue on their original courses, and subsequent traffic is routed based on the status change.

When does source based routing conflict with static routing?

Transactions composed of multiple packets might be disrupted or delayed if the status of source-based routing changes during transmission. Source-based routing can conflict with static routes. If a routing conflict occurs, source-based routing rules are prioritized over the static route.

When to enable or disable source based routing?

You might enable source-based routing if you have a large network with a complex topology. For example, if your network is a multi-tenant environment with several gateways, traffic is more efficiently distributed with source-based routing. Related tasks Enable or disable source-based routing
