| NexthopGroupType |
|
| A nexthop group is associated with a type, which determines
the packet forwarding behavior.
Type 'ip' refers to L3 IP routing. A route pointing to a
nexthop group in this case is equivalent to multiple static
route configuration entries each with a particular nexthop.
Types 'gre', 'mpls', 'ip-in-ip' all refer to tunnel types. In
this case a route pointing to the specified nexthop group is
used to tunnel packets using the appropriate encapsulation to
a tunnel destination. The encapsulation information depends on
the tunnel type itself. |

| aristaNexthopGroupMIB |
1.3.6.1.4.1.30065.3.21 |
| This MIB contains information about NextHop Groups (NHG).
General L3 routing creates routing table entries, each of
which are associated with a nexthop. If multiple paths
exist for a specific route, the route points to a set of
nexthops (commonly referred as ECMP or Equal Cost
MultiPath).
Arista devices support a feature which allows customers to
manually create a nexthop list, and use this list to
route packets to the specified set of nexthop
addresses. Customers can associate a tunnel type (GRE,
for example) with the nexthop group, allowing relevant
packets to be tunneled as well. The packet forwarding or
routing decision happens in hardware.
Nexthop group feature gives customers full control of how
a route should be forwarded (tunneled or otherwise). The
number of entries in the nexthop group is also determined
by the user, and directly translates to the number of
nexthop entries in the hardware for the specified route.
Let's provide an example, looking at EOS CLI example.
nexthop-group foo type ip-in-ip
ttl 64
entry 0 tunnel-destination 10.1.1.1
entry 1 tunnel-destination 20.1.1.1
!
ip route 30.1.1.0/24 Nexthop-Group foo
In the above configuration, any packet destined to
30.1.1.0/24 will be forwarded by the nexthop group
'foo'. Each entry inside the nexthop group specifies a
particular nexthop ('tunnel destination') chosen by the
customer. In this example, packets can be forwarded via
either of the nexthop (traffic split equally between the 2
entries).
This MIB module provides information relevant to the
nexthop group feature, specifically the status of various
nexthop groups configured, and traffic statistics. |

entry specifies a particular nexthop through which a packet
can be forwarded. There is packet and byte counter information
associated with each such nexthop.
This table represents the per nexthop counter information for
every nexthop group. |

| As described in the beginning of the MIB module each nexthop
group can have multiple entries, one per 'destination' or
'nexthop'. Each entry within a nexthop group has a number or
index as configured by the user. This MIB object represents
the entry index within the nexthop group. |
