Report the routes metric in IPFORWARDMETRIC1 and return
-1 for the other metrics as required by the IP-FORWARD-MIB.
inetCidrRouteMetric2 OBJECT-TYPE
SYNTAX Integer32
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"An alternate routing metric for this route. The
semantics of this metric are determined by the routing-
protocol specified in the route's inetCidrRouteProto
value. If this metric is not used, its value should be
set to -1."
DEFVAL { -1 }
::= { inetCidrRouteEntry 13 }
I've included metric2 but it's the same for all of them.

The snmp walk of the zebra rib was skipping entries
because in_addr_cmp was replaced with a prefix_cmp

A double-free crash happens when a subTLV of the "Router Capability"
TLV is not readable and a previous "Router Capability" TLV was read.
rcap was supposed to be freed later by isis_free_tlvs() ->
free_tlv_router_cap(). In 78774bbcd5 ("isisd: add isis flex-algo lsp
advertisement"), this was not the case because rcap was not saved to
tlvs->router_cap when the function returned early because of a subTLV
length issue.
Always set tlvs->router_cap to free the memory.
Note that this patch has the consequence that in case of subTLV error,
the previously read "Router Capability" subTLVs are kept in memory.
Fixes: 49efc80d34 ("isisd: Ensure rcap is freed in error case")

When an NHRP peer was forwarding a message, it was copying all
extensions from the originally received packet. The authentication
extension must be regenerated hop by hop per RFC2332.
This fix checks for the auth extension when copying extensions
and omits the original packet auth and instead regenerates a new auth extension.
Fix bug #16507

If the link-params are set when the circuit not yet up, the link-params
are never updated.
isis_link_params_update() is called from isis_circuit_up() but returns
immediately because circuit->state != C_STATE_UP. circuit->state is
updated in isis_csm_state_change after isis_circuit_up().
