Detailed Description

Internet Protocol Version 6 Stack.

Constructor & Destructor Documentation

IPv6()

IPv6::IPv6

(

uint16_t

nrt = 0

)

Initialize IPv6 functionality.

Parameters

[in]

nrt

Number of main IPv6 routing table entries

Member Function Documentation

addRoute()

error_t IPv6::addRoute	(	const IPv6Address *	prefix,
		uint8_t	prefixLen,
		IPv6Interface &	egressInf,
		const IPv6Address &	nexthop
	)

Add an IPv6 route to the main IPv6 routing table.

Parameters

[in]	prefix	Destination prefix
[in]	prefixLen	Destination prefix's valid length in bits
[in]	egressInf	Egress IPv6 interface ID
[in]	nexthop	IPv6 address of nexthop

Returns

• ERROR_SUCCESS: Success
• ERROR_FAIL: Failure due to table full

getRoutingEntry()

error_t IPv6::getRoutingEntry	(	uint16_t	idx,
		IPv6Address *	prefix,
		uint8_t *	prefixLen,
		IPv6Interface **	outInf
	)

Get an IPv6 routing entry.

Parameters

[in]	idx	Index of the routing table. If it is out of range of the table, the default entry will be returned.
[out]	prefix	Pointer where the entry's prefix will be stored at.
[out]	prefixLen	Pointer where the entry's prefix length will be stored at.
[out]	out_inf	Pointer where the entry's output interface pointer will be stored at.

Returns

• ERROR_SUCCESS: Success
• ERROR_INVALID_ARGS: Arguments are not invalid.
• ERROR_FAIL: The entry of the idx is not valid.
